Input on Building a 427BB Street Motor

[markjohnson]

I'll start this up. A 427......I'd use oval port heads for starters. It's a proven fact for camshafts .650 and smaller, they are superior. GM #781 or #049's work great. A set of Merlin OVAL port heads would be even better and there's a lot of used sets out there these days. Just make sure they've got the 2.19/1.88 valves. I'm NOT a very big fan of hydraulic camshafts. A solid is well worth the little bit of trouble of lashing the valves once a year and you'll look cool to the neighbor kids doing it. If you really wanna have some fun, stab in a Comp Cams 288 Street Roller that is incredibly street-friendly and will just tear your head off your shoulders at any RPM. Trust me on that one, it's WELL worth the money to step up to. As far as intakes go, the Edelbrock Performer RPM's (especially the Air Gap) just can't be beat for a street car. Nothing left to say. Intakes are fetish of mine and I have tried MANY. There's lots of terrible ones out there. I also like the Holley 950 HP Double Pumper #80496, but an off-the-shelf 750 or 850 Double Pumper would be fine. A good ignition, fuel system, 10 inch street convertor with a 4.10 rear screw and this car can run mid 11's all day long after being driven to and from the track. I've had the 468 CID version of this motor and it was so much fun, I'm lucky to even have a driver's license still!
