It will be in a 1965 Valeant 200 Signet with a Pro Trans 904 and probably a 35 spline Dana 60 pickup housing cut down and made for this deal with leaf springs, I will run it on the local E85 pump swill so I hopefully won't have to wory about detonation running the turbo boost up to 10 Lbs. or less using one of Holley's EFI direct port injection, not throttle body injectors. I'm planning on using this car to learn EFI programming and data storage and use it for tuning this motor My questions are anyone else using E85 with a SB turbo motor on here What mechanical compression ratio and cam specs information would be very helpful Thanks in advance: Cab Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

I have a 470 with a measured 10.0:1 compression ratio. Home ported Edelbrock R.P.M. heads. Holley Sniper X-flow. Cam is a Bullet s.f.t. 247in.251 ex @.050",.546-.540 lift with a 115 lobe sep. angle. Bought it from Little john motorsports after sending them all the info on the combo and intended use. I looked up the lobes in their catalog and it actually has a Ford .875 intake lobe and a Chevy .842 exhaust lobe. Told them this is a 100% streetcar and didn't need anything that would beat up the valvetrain for 4 extra h.p.. In. opens 12.5 closes 54.5 . Ex. opens 64.5 closes 6.5. I run it at around 12 lbs with timing in the low 20's. I have had it as high as 17 lbs., but don't need that much extra tire wear. Last edited by 67_Satellite; 03/19/24 05:04 PM.

I don't see why the same concept would not work on a 5.9 magnum stroker. The "sloppy stage 2" cam from Elgin is commonly used. Last edited by Craig J; 03/19/24 08:12 PM.
