I'd like to thank everyone for the advice I've gotten here on my heads and cam - and in particular Mike Wolf and Micky Hale!
Started with a standard bore, factory 2 bolt shortblock BB (454), 10:1 CR, with 049 heads (slightly worked with 1.88/2.19 valves) and a Crane hydraulic cam, Performer RPM and spreadbore 750 Holley, headers (1 7/8" primaries/3 1/2" collectors into 2.5" pipes and Dynomax turbos. Based on dyno results, was cranking out just under 400 hp at the flywheel.
Block is now 30 over, honed, factory steel crank and rods, Wiseco pistons, Comp solid roller cam, AFR 305cc heads (partially cnc'ed, 1.88/2.25 with titanium retainers), new Performer RPM, Holley 830 DP. 11:1 CR. Exhaust is ceramic coated Doug's headers (2" primaries/3.5" collectors) into full 3" Pypes CC system with their Race Pro mufflers. Rotating assembly will be balanced and cam degreed in at the machine shop. Should be done in about a month, and back on the street by next Spring, I hope, after Micky finishes the full resto!
Got the AFR's through Mike Wolf. He promised them in 6-8 weeks. They'll be delivered today in less than 4! Mike was great to work with - was very patient with someone who knew/knows very little about performance parts in specing them out! Didn't push AFR's, but by getting a thorough understanding of our objectives, helped us narrow the selection to the 305's. I couldn't be happier!
Micky and my son son Mike worked closely on the cam specs. Here's the basics:
MFG: Comp, but custom spec'ed by Flowtech Induction (Ed Curtis)
Style: Solid roller
Lift at 1.70: .646
Duration @.050: .242/.248
SEP: 110
We're hoping the combination will result in between 550 and 600 hp! Quite a change!! And none of it would have been possible without the help of all those who offered advice here, my son Mike, Mike Wolf and Micky.
Thanks to all!! I'll let you know how she runs next year!!
