Motor blew up next build ideas

[Twomuchsmoke]

What’s up guys I’m not sure if I wanna go ported stock crank or 4 mil , I was really looking into going 4mil stock cylinder but everybody tells me to go ported serval from redline but i serval cylinder kit is so expensive compared to a driveline 421 setup.my question to you guys should I go stock stroke ported,stock cyl 4 mil or serval or driveline cylinder. I will be doing supporting mods like ,cpi or hand coned pipes,pwk  28 but might go bigger 33-35mm pwk, stock oem head cut and modified since it’s new condition bought it before I was gonna go 4 mil.+4 timing,driveline hd clutch and hd springs.v force reeds v3 or v4 depending if I can find a good deal. I just find a serval or cub a lot of money if a driveline cylinder can give you similar power for less money that can be spent somewhere else. I also ride trails,street,track, open field and power lines riding a lil bit of everything honestly .the part of Florida I’m in has a lot of sugar sand.

And for hand cone pipes I’m going with Kenny roberts.

Save a ton of money and get either Shearers or CPI instead of handmade pipes.

id go stock cylinder, stock crank (welded) vf4 reeds and 28 pwks. 
 

If your wanting bigger have driveline do the job.

Id do regular stamped pies and put the money toward suspension and tires. If you already have that, then save the money. I would get with driveline if that's the cylinders you want. They can tell you which carbs and pipes will best suit you.

I had a 4 mill oem dune play port from F.A.S.T years ago. It has pwk 35s, cpi pipes and it was a perfect motor for trails. Sold it for a Redline 4 mil serval and didn't care for it. Then went to a 10 mill redline ported cub. The 4 mill dune play port was a dam good motor and better then my 4 mill serval.
