Hi guys, here's the parts I have so far....
360 block 4.060 bore ('71 casting) already blueprinted and ready for assembly
4.125 crank
6.2 rods
zero deck pistons (with 17cc dish)

would like to go hyd roller cam and aluminum heads
also will be some type of efi....

engine will be going into AAR with auto and 3.91's...
car has power brakes
would love to have 500hp/500tq, but realize that might be an optimistic goal, more importantly to be happy on 87 octane E10
send me some thoughts on how to finish this thing up (cam specs, comp ratio, heads, etc)- Thanks!



The 500TQ won't even be a challenge... That's just a mathematical given @ this point. & 500 HP would'nt be too tuff either. Edelbrock head, little clean up work & mild hyd roller & you'll be right there. Compression ratio for 87 motor will be dictated by cam secs. Cam specs dictated by the power brakes, converter size/stall etc.

We just had a 393" Ford trick Flow head motor on dyno the other night & ran it on 87 octane after tuning it on 92, just to see what it did. 165 cyl pressure, it was fine on 87. @ 34 degrees. I run 87 almost exclusively in my INDY EZ head 440 @ 9.7:1 242/246 Hyd roller motor. ~600 HP, 38 degrees, it's never detonated. I also used to have a SB 410" Edelbrock that I ran on 87 in a daily driver... I think that one was around 9.7:1, & cam was in the 236 @ .050 range on 110 LSA in @ 106. That thing had 17" vacuum, as I ran power brakes in that truck... put like 5000 miles on it & sold it because fuel economy sucked.

Really only stuff we build for 87 Octane is daily driver type deal... that's where the cost difference between 87 & 92 really shows up. On the weekend toys, usually do a 92 motor.
