replacing 88 270hp 350 mag alpha, w/bravo
sbc build. WHAT A PROJECT !!
Thanks again,

You picked the right guy to spec your cam! Bob is the man!

I think you will be very happy with your setup and keep us updated on your numbers.

Bob Mardera also spec'd my cam for my 385ci. We figured with dyno headers right under 500hp @ 6000rpms.
It runs excellent and idles @ 650rpms in gear and 800rpms N. Has pushed my Challenger to 80.5 GPS @ 6300rpms.

Here are my specs for comparision....

010 4 bolt SBC, bored .040", 0 decked, line honed,
ESP 4340 3.750 crank, ESP 6" 7/16" H beams, Mahle forged FT's 5cc, C77H bearings, Hines Balanced
Melling Racing #10555 oil pump, Hamburgers 7qt marine pan, full length windage tray.

FluiDamper harmonic balancer,
AFR 190cc heads, 73cc, further ported by Carl McQuillen Racing Engines, Isky 6105 dual valvesprings,
Marine Kinetics "RMbuilder" custom Hyd Roller 234/240 .580/.568 112+4
Morel Retrofit Hyd Roller lifters
Smith Bros .083" wall pushrods
Edelbrock RPM Air Gap port matched to AFR port
Holley HP 750 DP
Lunati Voodoo Widebody 1.5 roller rockers
