papa_smurf49319 Posted May 27, 2004 Report Posted May 27, 2004 My 350 in my 1990 chevy pickup is getting a little tired, i just put a body lift on and am running 33*12.50's, i also put a turbo 350 trans in it, and now am having a guy rebuild me a 383 stroker, out of a 4 bolt main block, and its suppose to have around 400-450 horsepower, everthing is going to be roller, and i could run nitrous if i wanted, but wont. Just want to have a little talk to get me reved up about it. Quote

Holyman Posted May 28, 2004 Report Posted May 28, 2004 I had a 383 in my 66 Charger and had one in a 71 Fury I had. I wish I had 'em back OH yeah... I forgot about the Challenger I'm gonna get me one of them back one of these days. Nothin' like a big V8 without all the wires and hoses Quote
papa_smurf49319 Posted May 28, 2004 Author Report Posted May 28, 2004 Ya i totally agree i love poping the hood on a vehicle and knowing where everything is and what everthing does, now its all electronic crap. Ya were puttin vortech heads on the 383, the builder said these are the best heads you can get. Quote
Yamahammer Posted May 28, 2004 Report Posted May 28, 2004 vortech heads are great bang for the buck but you hacve to run a vortech intake to match the head harder to find a performance intake foe it and more money does not accept the same as a standard small block chevy.. the bolts are in a different location. are you going to keep the throtlebody injection or change to carb. unsure it the throtle body will bolt up to a vortech manifold and if it has all the ports for the fi. 383 are good motors make a shit load of torque 400 to 450 sounds a little high expect about the 375 to 400 out of it but still a substantiol increase over the stock 350. are you going long rod or short rod was the block a previous roller motor ie a late model 350 or an early 350 2 piece rear main ore one.. shit the list goes on and on.. post some more details of the enternals crank so on...

bigtreads Posted May 28, 2004 Report Posted May 28, 2004 I have one in a Land Cruiser on 44's and I love it . I wouldn't trade it for any big block. You won't be disapointed. Why chevy never offered it as a option I'll never know Quote
boonman Posted May 28, 2004 Report Posted May 28, 2004 The #'s yamahammer posted is what I was thinking around.. I have helped build a couple. lots of "relieving" (ie. grinding) on the block at the oil pan gasket area to clear the rods. Strokers in a Small block are an EXCELLENT truck motor. And I don't know about the nitrous. I would run that on a stock stroke 350 before I would run it in a stroker...... strokers don't rev like a stock stroke...... The vortech heads as mentioned are a good bang for your dollar, but intake choices, or rather lack thereof is what turns me away. I have a pair of Bowtie heads, swirl ported that will outflow ANY vortech heads I have seen. And I can run ALOT more intakes. The choices are endless. I think you would have been better off to get ya an older set of heads, and port them, and stick a set of valves in there.... But, a stock pair of vortechs would be cheaper. I am fairly certain you can get an intake for either a carb, or throttle body injection that you already have... i just dropped another small block in my S-10. This one is a lot less powerful as the other one that was in there.. Lower compression, and a milder cam. Oh well. Fuel mileage is good. I have a 700 R-4, that I wouldn't trade for the world...... OD and it burns the 32-11.5 SX swampers into second!!!!!! I have to launch it 4WD!! Anyways, you should be happy with the stroker. Especially coming from a tired 350. What kind of cam are you throwing in there?? Quote
Ducman Posted May 28, 2004 Report Posted May 28, 2004 I had a 383 in my 66 Charger and had one in a 71 Fury I had. I wish I had 'em back OH yeah... I forgot about the Challenger I'm gonna get me one of them back one of these days. Nothin' like a big V8 without all the wires and hoses Your talking about 2 different motors there, ones a mopar bigblock - bad ass, my dad had a 69 superbee with with a 383, the other is about the most kick ass modified chevy small block you can make, a 350 ci running a crank out of the 400 ci motor. You don't need nitros, with an all roller motor 383 stroker, some high lift cam lobes with steep ass lift angles, monster valve sizes, its gonna friggin rip, 400 hp no problem. You'll want to feed it a lot more fuel than your stock fuel system probably will. Also if you use the stock heads you'll want to port the hell out of them. Quote
papa_smurf49319 Posted May 28, 2004 Author Report Posted May 28, 2004 ya im switchin over to a carb, im thinkin of puttin on a quadrajet 4 barrel that my dad has sittin in the garage, but ill most likely end up puttin a holley truck avenger on there in the future, i have no idea about the whole block thing yet, all i know is that it is a 4 bolt main, with some performance mains, and it has been magnafluxed, its goin through the whole process. My dad knows the guy that's buildin the engine, and he said the last 383 that he built for a guy was makin about 400 horsepower on the engine dyno. Im not going to spend that kind of money, he told me for what i wanted id be makin around 350-375 horsepower. If he cant find a set of vortech heads, then where just goin to clean the ones that i have in my truck up and through those on there, the man said everything in this motor will be roller. I have to get some more details on it today. I just went down and talked to him for a bit, and saw the block. Boonman have you done anything to your 700-r4? i havnt really decided on the internals yet, But i am most likely going to buy a rotating assembly from www.ohiocrank.com Quote
papa_smurf49319 Posted May 28, 2004 Author Report Posted May 28, 2004 If you go to my website you can see the buildup on my truck, i will have motor pics on there when its done. I still have bodywork and a rear end job i have to do yet Quote
Yamahammer Posted May 28, 2004 Report Posted May 28, 2004 Truck avenger is good if you can find a good servicable 750 secondary i would go that route the avangers are a litttle hype in my book. Do you plan a 4x4 in it seriously and up steep hills if so keep the f/i find out what roller rockers he is using and the ratio. make sure he is not just saying a roller cam and or a double roller timing chain, and if it is a hydrolic or a solid roller. If you ditch the f/i you will need a new distributor also the current one you have is electronicly controlled as well as a new coil. try to find a pair of heads or buy a cheaper set of aftermarket heads the stock heads are junk so putting all that in the bottom end will kill the performance of that motor. it would be the same as a 12 mill strroker banshee with stock cyl and stack carbs not a good combo. find out what kind of rings he is using before you put the juice to it if you ever plan on it, and just remember every time you hit the button you are taking potential miles off the motor Quote
papa_smurf49319 Posted May 28, 2004 Author Report Posted May 28, 2004 I believe it is hydrolic, and hes one of my dads good freinds so ill believe what he says, ya he said that the stock heads are crap because gm doesnt clean them up after casting, but he said if it came down to it, we could clean them up. Ya and i dont plan on using nitrous, he said i could if i wanted. I plan on doing some good offroading time, but not insane, i still want to be able to drive it back and forth to school everyday. I belive he is giving me a ignition kit and distributer. Quote
boonman Posted May 28, 2004 Report Posted May 28, 2004 Indeed. My R-4 has a few mods to it. 13 vane pump, .500" Boost valve, B&M strip shift kit, New 2nd gear apply servo, (larger than corvette size that everyone uses) 2500 stall lockup convertor, 29 element sprague, 5 pinion in and out planetaries, biggest tranny cooler B&M makes. Gotta keep an R4 cool. I am a little perterbed because my rig WILL NOT shift untill it hits 3500 in any gear. And after everything warms up, I get no 3-4 shift. I dfon't know what's up yet.... I just got it together Monday night.... Or was it Tuesday.... I think Tuesday.. Anyways, the truck avenger is a good carb. And should be PLENTY for what you want to run. And like mentioned, if you can't find a vortech head, Don't use your stockers unless you prt them and completely rebuild them. And at the price your gonna shell out, you could have some brand new pre-assembled heads that will smoke your stockers... What cam you gonna use? I am currently running a Holley 600 vacuum secondary. I have a 750 Holley on the bench, and an Edelbrock 600 as well. Actualy, I think the Edelbrock is like a 580 or something like that? I don't quite remember. The Holley 600 is brand new. That's why it's on there. I don't want ANY problems on the way to Coalfest. We'll see how it runs this weekend..... My tranny is thie shit though. I love it. Once I get the bugs worked ot, it will be sweet... Quote
papa_smurf49319 Posted May 28, 2004 Author Report Posted May 28, 2004 havnt decided on a cam yet, but hey do you have any pics of your truck, whould love to see it Quote
