I am having my computer reprogrammed for 30lb svo's with stock fuel pressure. I have ported LE1 heads with a valve job done on the stock valves. I am using a 306 instead of Lloyd's LE1 cam, which I believe the 306 is bigger. Now as of right now I am using shorty headers, but shorty or longtubes my FLYWHEEL horsepower will still be the same and I have a feeling that the 30lb svo's will not be enough. Do you think I will be running more than 425 flywheel horsepower? If so do you think these 30lb svo's with stock fuel pressure is enough? Thanks for any help.

 

The 30#s will be way more than enough. And how do you figure you flywheel hp will be the same with lts. Rwhp is only gained because fwhp is gained.

 

I was always under the impression that by going to headers you just free up horsepower going to the wheels and not to the flywheel therefore I figured longtubes freed up more power to the wheels compared to shorties. I didn't know it freed up the flywheel horsepower. But now that my fool self thinks about it the flywheel would turn easier if the exhaust could escape quicker.

 

Its ok we all get a little confused sometimes. Btw how do you like the 306 and le1 heads...i may be doin the same thing.

 

Well, I redid my whole engine with forged internals, the LE1 heads and 306 cam and just now got the engine back in the car and will be starting it up next week when I get my computer back. So I can't tell you yet, but I can pm you next week to let you know.
