Come to think of it, i have a set of killer 440-1 heads, 1.7 jesel rockers, and most of the parts to build a 580 inch street bruiser! Ok, now to find a perfectly clean Chrysler Imperial, 😁
Something similar to our street/strip combo 589ci wedge motor @10:1cr, a small .625" 260/270@.050 s/roller motor, 440-2 intake but with race 365cnc -13 heads, made 720ftlbs@4400 and 694hp@5500 at 33 deg.total and with a small old 950DP,....runs on pump V-power and should last well as its shifted@5800 and traps at just over 6000. Potential there for at least another 100hp with 2+points cr, more cam or even 1.7 jesels and a Dominator.
What about part throttle response and low rpm cruise?
That's where peak numbers mean nothing. Gotta make solid vacuum for power brakes and to keep the EFI in its happy place.
Throttle response is excellent, can't get into it at all without lighting the street tyres up though which I've never seen him do, car has 11" drums and no power, stops the car good, owner goes to shows with it, low rpm cruise is fine, we adjusted the carb using vac guage once at the track, it had 15" if I remember correct@around 900>1000 for what its worth. Its driven to the track and raced with full exhaust to bumper, I don't think he could've got a much better deal (£10k for the fresh motor) as its fulfilled all his requirements and more on track, but with that came the added expense of a Dana, a race 727/converter etc. etc.
