What do ya think?

O.K you guys tell me what ya think about this set up..

I have a 91 350 TPI, I am keeping the stock plenum and just porting and cleaning it up real good, I have Slp runners and Accel intake, I ordered a set of AFR 190 heads milled to 64 and they have the spring upgrade, Msd digital 6 and msd coil, NX wet kit (35-150) I think I am going with the LPE211 cam .211/219 .530/.560 *112 with 1.6 rr's, she will be getting new rods and pistons and I will get the crank checked out

How do you think she will run??Am I missing anything?

A good timing chain or gear drive.

New lifters and pushrods obviously.

Injectors?

Im thinking at least mid to low 13s. Have you dont any suspention work yet? If not I would cause your gonna need some traction. Maybe you could be in the 12s if you can hook. Also your gonna need some prom burning as well.

Yes I will get a good timing chain and get some new lifters, also I was thinking SVO 24lbs injectors.

All my susp. mods are in the sig.
I also have some SLP headers and the rest of the exhaust will be replaced, Dont know if I will keep the cats or not yet.

Thanks for the info though
