440 question
My pops used a 18,000mile 413 from a motorhome for his twin turbo dream... It is finally finished. The 413used the orig. pistons that looked like soup bowls! Compression is somewhere around 7.5 to 1 with the 906 heads. Perfect for his twin 67mm Garret turbos. We did a desktop dyno on this combo and it produced
1100hp@20lbs boost. Don't laff at me yet! It has a custom grind cam, M1 intake, heads have been worked over. 850cfm blow thru carb and a intercooler from a Furd truck. Turbos are mntd to hooker fenderwell headers. had to do a little work in the cowl to allow room for the turbos. He only has around $6000 in the build of this setup. Turbos and the intercooler are used..
Anyhow,
cam, headers, intake and carb will get ya 100hp over stock. Around $1000 to $1500 for these bolts-ons..
Down here everyone is going to turbo engines. Easier on the engine parts than N20...
