Will it be possible to get 600-700hp from a stock 5.3 lm7 with truck manifolds and a single turbo conversion?

What cam and intake would be best for the job?
I will drive it on e85 and rev about 7000rpm, please help me what more parts I need, This will be a budget build. I also want to have some ideas about the fuel system.

Later I will build a forged engine but I want to play earlier
Will it be better to get a 6.0 lq4 to build then the 5.3 lm7 I got now?

I have already order a t56 magnum I will use with it. Im thinking of use a spec 3+ clutch.

 

Crank or rear wheel? That's a big difference between the two.

 

thats kind of a small turbo dont you think for 600-700hp on a budget build?

 

what turbo? I meant the gearbox is a t56 magnum and I meant 700 on the crank.

I have think about a gt45r china turbo and try it. I read about people running 8s and 9s with it.

 

Lol I guess they didnt realize that a t56 is a trans.

Yeah I think its possible to get 700whp. Im no cam or intake expert so i cant help much there but I have alot of faith in these GM engines making High HP

 

7k rpm on stock cam and springs?

 

I read somewhere that a ls6 cam would be good and patriot gold springs. But Im new to v8s so I donīt realy know.

 

You better plan this project out well...


typically the 6.0 would be the builder block. Yes it is possible but the engine will not last long depending on your driving style.

The ls6 cam and springs will work in a N/A application to 7k, but I would be worried if you are boosting an engine to 600-700 hp, I bet the lifters will begin floating....

 

Ok but what parts are the guys use that are running 8s and 9s with budget build lm7s?

 

I dont see being able to run 8s and 9s if your on a budget. If I'm going that fast, I know I really wouldnt want to be skimping on parts.

But, 700 crank HP is surely possible. Im almost there as it is on my build. We averaged mine out to be a lil over 650 crank HP. But, I wouldnt take the chance of it lasting an extended period of time making 700+....just my 2 cents.
