I dropped my motor off at the shop yesterday and they plan on cleaning and checking it for cracks today. So I figured I should start getting a game plan together. It is going to be a street car, not daily driven but driven a few times a week around town. Goal is 525hp street brawler that sounds nasty.
Car specs (1969 GTX)
727 auto
8.75 rear with 3.55 sure grip rear
440 block is a 69 hp block
Stock front suspension
Mopar s.s. springs rear
Forged crank, stock stroke.
Stock rods
Keith Black Pistons from Hughes KB237, size to be determined. Used with the Stealth heads, should yield a 10.6:1cr depending on gasket http://www.hughesengines.com/Index/...Q==&searchmode=partnumber&page=6&partid=27949
Hughes solid lifter cam STL 4246BS3-9
http://www.hughesengines.com/Index/...&level2=RmxhdCBUYXBwZXQsIFNvbGlk&partid=30278
Hughes EDM lifters 5012
Hughes 1128 springs
Stealth Heads (80cc). I like these better because of the straight plug placement and sealed water jacket under exhaust studs. Plus they look stock and I plan to paint the entire motor hemi orange for a stock look.
Edelbrock Performer RPM high rise dual plane intake.
850 Demon carb.
Headers (looking at Summit or Jegs brand)
ARP con rod bolts, cap studs, and head bolts.
Mancini Racing Adjustable Rocker Kit, 1.5:1 ratio, MRE 57001-15-714
Ball / cup pushrods
Thoughts? Opinions?
My reasoning on solid vs. hyd cam.... love the sound, higher reving, no worries about bleed down or pump up. And I am buying the adjustable rockers regardless. Spring pressure is higher with solid but within specs of rockers and the springs are a matched to the cam. I will listen to any advise.
Pistons...anything elseworth looking at? Are forged needed for my build?
Thanks,
Mark
