Budget build. $4K = 10's

Mike, I dont know this to be true for the 6.0L or not, however I’ll tell you a brief story:

A buddy took a carb’d 305 out of his third gen and put a carb’d 350 into it. Seems simple enough. However, my 97 non-supercharged Grand Prix pulled on it over and over, and that car luckily hit 15.4.

Meow. The catch is, after this happened a couple times, he did some homework. The 350 came from a K10 thus being a truck motor, the heads were built more for torque than power so his neato burnouts were all the car could do. The car 350s had a different flowing head.

My warning, or question, is since the 6liter you’re getting is coming out of a pickup (presumably a Chevy HD?) that is totally built for hauling lots of shit, not fuel economy or going fast, dont you think the car will be a bit slower than you imagine?

Its kind of apples to oranges. The old skool 350’s had millions of configurations, since they were around for 50+ years.

Think of it this way. Look at a 98+ camaro with the LS1 and what they do. The block I am using comes from the same mold. But mine is a 6.0l and they are 5.7L. +1 for me. Heads actually flow more than the LS1. + 2 for me. For forced induction less compression is better for higher boost… mine have less compression than the LS1’s. +3 for me. Truck manifolds have a bit more TQ but still flow as well high end as the LS6 intakes, both better than the LS1. +4 for me. Aluminum LS1 block is 75lbs lighter than mine, minus 1. The iron block is stronger, and if it blows a piston apart, I can bore it and put forged pistons in for cheap, and make moaaarrr powers! Aluminum block cant be bored they are junk if something comes apart. another + for me… leaving me at +4 over the LS1 with same turbo setup in the same car.

Thanks for the thoughts though, so dont take my reply as a rib poke, wasnt ment to be at all… just answering your question.

@jdaniels

The LQ4 heads are 317 castings which flow almost identical to the 243’s that are on the LS6 motor (read: flow a ton better than LS1 heads). They have larger chambers which keeps the compression ratio down (good for this project obviously) and make great power. They share the same crank and all other parts, the block is iron instead of aluminum (~75lbs heavier) and the bore is larger. They generally make a little more HP/TQ than the LS1 with the mods being equal.

And theirs the tech to prove it. :number1
