i am pretty sure my motor needs to be rebuilt and im about to compression test it before I move foward. But i am thinking i will rebuild it back to stock, bigger turbo, larger stall conv ertor, fmic, 3" dp, ported exhaust manifolds,ulmtimate chip, new everything else. I think i can do everything but rebuild the actual motor,so i will probally pay a shop to build it. My First question is to rebuild it to stock specs what should my new internals consist of? Second is if my truck is running should i take the motor out, take it to get rebuilt, and then put it in myself. Or should i drive it to wherever it is getting built( probally not a syty specialist)?

Re: engine reuild

Internals.. well that depends on your budget.

I don't see why taking out and reinstalling would be a problem if you have the space, tools, and time (as well as patience).

Re: engine reuild

I'm not too big of an authority on what to recommend, but Eagle rods, SRP or TRW pistons, a set of L35 heads, a 412-ish cam and one size overbore won't damage the wallet too bad.

i think im sticking with stock heads and cam for budget and tuning reasons, and ill only bore it if my rings have ruined the block too badly. If i were just building a block to stock specs what would the part list include?

Re: engine reuild

L35 heads FTW! I don't know/think it will throw a monkey wrench in your tuning and are a modest and cheap way of gaining a lil more power.

I hear ya on the cam.

For rods, I think eagles are a good way to go, but require clearancing the oil pan a touch. I think the L35 engine rod is a modest upgrade as well, so try a search on them for more info.

I also hear ya on resisting an overbore. If it is clean and can be smoothed out with a hone, then that is all good too. Whoever rebuilds it will get the specs on the walls and tell ya if it is necessary.

wait so do l35 heads require any custom tuning, i thought you needed a new cam to match? will heads raise the revs?

should i get it bored .30 over? sytyperformance does that to there stock engines they sell and many are recommending it, why is that?

and is it worth going 4 blot mains?

Re: engine reuild

I don't believe you'll need any tuning for them, but I think they flow a lil more and I heard a syty vendor say they're good for 30hp. I'd do a search, and take my words with *2* grains of salt. The vortecs will require some manifold mods, but the L35's are a direct bolt up. I'm sure by the time everyone gets off work and starts posting there will be a lot more insight/advice on that.

4 bolts are always nice, but another syty vendor said keep the stock crank tight and it'll be fine.

I mentioned the cam because you mentioned an Ultimate Chip upgrade, but then again, there are different versions.


I guess it all depends on how rad ya wanna get (goals). Are you planning a turbo upgrade?

yes im planning on a larger turbo, i would love to add heads and cam to my build but i dont think i have the time and my location makes tuning very hard.

Re: engine reuild

stock rods, forged pistons-TRW's, stock crank, add arp main studs instead of bolts, Melling M select oil pump stock press/volume, doulbe roller timing chain, l35 heads, either stock or 412 cam

the normal rebuild parts- bearings gaskets etc.

exh manifolds dont reall need porting, maybe opening up the exit to the turbo, thats about it.

cool and does the 412 require custom tuning or is there a bolt on 3 bar like an ultimate pre made?

Re: engine reuild

Re: engine reuild

ultimate versions are made for 412 cam and l35 yes, and someone can program one for you for relatively cheap also

the 412 is the least aggressive aftermarket cam that is a common part on a syty rebuild around here. might be able to find one used, and l35's are cheap 50-100 if you look around, stock victor head gaskets and bolts should be fine, you can get head studs if you have the extra money also.
