Anybody ever seen this article. 400 torque from around 2500 to 5200 rpm. about 400 hp.

11:1 compression tells the story.

I might just build this instead a big block... I like the torgue band for towing which is what I plan to use my truck for. I have buddy that builds race engines and I'm gonna see what it will cost to build through him.

I'll post back with his thoughts on this

I can see this was printed in 97 .. now you can pick up a 383 rotating assembly from Scat run the same cam or even better a split duration with more lift and the connecting rods will be less money with no mods and it should make 450 with ease.....

joedoh hit the nail on the head... i had a 11.25:1 327 with a tunnel ram, oh, a FEW years ago. It was fast, but I could barely make it between gas stations and the hi compression had me going broke with 104+ octane booster. Luckily I lived near a dragstrip - they had some 108 at $5/gal - and that was 1980. Anyway, the track is closed, I've moved west, and I will never, ever again build anything with anything close to 11:1 anything.

I have built almost that same motor only with a 6.125 rod and bigger cam(In my head and on paper) The rods and pistons are pricy! The long rod does help with detonation i can attest to that.

they also usef a detonation sensor, but what was the fuel mileage ?

I think we could buy a computer controled 6.2 and get the same hp and better fuel mileage......in a vortec engine.
