H129 Crankshaft and 795 series pistons

[raptorooster]

Hey guys, So after tearing my engine down getting ready to do the Cub I realised that I spent a little bit too much on my supercharged slammed big block dually Chev project and with a kid on the way am risking getting my girls shoe in my ass if I shell out the money for the Cub's. I have a rattle in the mag side rod so I have been considering just doing the following, I just need to know if there are more parts required that im overlooking?

 

Hotrods H129 Crankshaft (5mil longrod 4mil stroker)

Wiseco 795 series piston (795M06500)

 

Now as far as I know the 795 series piston was designed to not reqiure a stroker plate by moving the piston pin up, is there anyother parts im going to need for this conversion? What I already have is:

 

FMF SST pipes

Trinity 35MM 2 into 1 carb with K&N filter

Trail ported stock cylinders

V-force 3's

Cool head with 17cc domes (this is a leaded 110 engine only)

Prodesign biller impeller

Aftermarket aluminam radiator

Dyna Fs ignition with Nology coil

200 watt stator with adjustable plate and HP flywheel lightened

 

Thanks for the space guys, If there is something im overlooking please let me know, Im just trying to make this a simple project that I can finish on a sunday and ride all summer without a problem! Is this setup going to make some power? Thanks alot, Ryan

You're somewhat correct...

 

The 795 is designed for the longer rod (115 vs. 110 stock length) not the longer stroke (58 mil vs. 54 stock)

 

So...that being said, you have two things you can do.

 

Run a spacer plate, or have stroker domes cut.

 

You said money was an issue...so, run the spacer. If you cut the head, the cylinders "Should" be ported/matched to the longer stroke.

Thanks for the information, After investigating further hotrods has a gasket available by cometic that is the appropriate thickness to run this setup without dome modifications. You have always been a great goto for banshee information. Hopefully this setup will make some power and run well untill I pickup the Cub's. Should keep the girl happy seeing as how I have spent some serious money on every toy I own over the last 6 months!! I would have to expect that there is goint to be a pretty healthy power difference between the longrod stroker and stock stroke and rod, I'm excited to find out! thanks for the insights and help with this one!

I'm running an almost identical setup cept I got my stock head cut and had the porting done to match the added stroke (no spacer plate). Jetting was a little tricky with the single carb but not that bad. My shee's got heaps of power everywhere now and I can actually lug it like a 4 stroke in case I miss a shift or am just feeling lazy. PM me if you have any questions as I'm not on here that much anymore.
