this is just a wha if question. what would it take if I put a ls1 in my truck to get to 450 rwhp on engine. Just wondering becasue i ma looking at finding a cheap used ls1 that I don't have to dick with to much. thanks for the info

 

Going na, i think it would be near impossible with the power lost threw the tranny.
with a power adder its easily do able. I bet low 400rwhp is possible with a cam/head combo with full bolt ons.

just my opinion

 

I think you can do it easily all motor but youd have to upgrade all internal engine parts. Pistons, rods, cam, heads i bet you could do it. Especially with a bopsted CR from the heads and pistons

 

Getting that to the ground would be on the edge or just below getting more cubes by doing an all bore or something. A friend had just over 420, I believe, to the ground in his f-body with all the bolt on's and a head and cam package with stock rotating assembly.

 

Well I could run my heads off the 5.3 that I have now and tweak the cam and p/p the 5.3 heads. Does anyone have numbers of what that might bring in hp. Just looking at a cost effective way of making power on motor.

 

The fbody guys are getting 420 rwhp from 5.3 heads and good cam.

 

start with a t-rex cam and......

 

this has to be streetable, becasue i drive 20 miles to work and back and will probably start pulling a 21 foot pontoon boat, so the cam can't be that aggressive.

 

If it is a matter of cost I would look at a 6.0 and a nice cam. 450rwhp in a NA LS1 is going to be tough. Id like to know of a cheap way to get there too. I'll be very pleased to hit that with a Vortech at 11#, alot of bolt ons, and a good blower cam.

 

yeah, I would probably be please with just getting around 400 to the rear wheels, but then you can always spray. Just want something a little different in the truckl but work great, and I would loose some weight. I've decided against a 6.0 unless one comes to me really cheap, then on anotehr thought????
