where are you located (for tuning purposes)??

the GEN 1's and GEN 2's are quite similar other than the opti spark, cam driven water pump and reverse cooling flow motor......other than that lot of gen 1 and gen 2 parts swap......you can run gen 1 heads on a gen 2 motor also without alot of changes....

Budget and Goals?

Building the LT1 from the mechanical sides of things is IDENTICAL to a SBC so if you can build a SBC you can build an LT1. Then comes some minor things when you get out from the bottom end.....Timing cover is different, Heads are different (Reverse cooling) and of course the tuning is way different. once we all know your goals your budget and what your doing with the car we can all take a stab at steering you in the right direction

I live in Tennessee About an hour from Chattanooga and An hour and a half from hunstville Alabama. As far as budget pretty well Not one because im building it a litle at a time during the winter i have a daily driver so its not like i have to have it right away. I mainly am building it because my friend says that his ls1 cant be touched by an lt1 which is crap because he only runs 7.7 in 1/8. And i ran a 9.8 on street tires.

9.8 is mad slow omg

But the goal is to beat him.........Or make him cry like a lil girl when you beat him?

You can spend 20k here or you can spend 5k here we truly need an idea of what your WANTING to do and what your WILLING to spend.

Im lookin at a cam still not sure what duration or anything im gonna go with. I think i have a 3500 stall lined up as well as a set of longtubes. I just orderd a set of 3.73s but i may change my mind and go with a ford 9 inch but i cant seem to find anybody here that can tune it when i do swap the cam in it.

PCMforless
Moe on here does Mail orders

If you plan on doing anything in the future with the car working from the back to the front is the way to go for sure........I did it backwards with my car and ended up being a bad thing. Suspension, Rear end, Tranny, Then bolt ons and a cam only car should net you CLOSE to the 7.7's

Both of them do excellent work from what I hear on here no personal experience with them so not going to vouch for either one in a pissing match of which is better but you have the right idea you need to get your times down now as they are because they seem ULTRA slow even for a stock car

If you just want a fast car its almost worth buying someone elses project.. you can find them all the time just make sure they have paper work and such and can be a drop in and save you LOADS of money
