here is the two options.

408 lq4. already have a machined block - spent 500 bucks can get that out of it
243 heads have sale pending for 440 can cancel that or buy them with prc dual springs for 700 installed
LS6 intake and TB off of current motor.
Callie 4" crank, 6.125 rods, wiseco flat top -3cc heads. 2k
236 XER cam on a 114 LSA from comp cams $350

-OR-

01 LS1 m6 vette 80k miles.
TF 205 heads 58 cc chambers. Fast 102 intake and throttle body
possible custom grind cam.

Regardless of which route i go A&A headers and Spec stage 3 clutch with HD t56 rebuild is going to happen.

The budget is whichever route will get me closest to 500 rwhp cheapest.

 

i always prefer more cubes.

 

Go with the newer block design..

 

Big is Best *

any help?
