Same deal. Large and small flywheel and the start has to match up. Angled bolting for the large flywheel and straight across bolting for the small flywheel and the bell housing for the smaller flywheel won't work with the large. And the flywheel bolting to the crankshaft might be different...
Should be no problem trimming the bosses off but be sure to get all the shavings/filings cleaned out really good. With the roller rocker arms there's usually not a lot of oil spraying around in there anyway so the baffles can go and not cause problems. Got some nice looking parts in that...
Might be some cold (range) plugs for the street rod running. What are they? Might go a number hotter but with the limited run time it's may be too soon to see what the deal is.
I remember my first, had a adivan to calm me down. Then the good stuff. When I came to a nurse was beside me reading a book. She asked me how I felt, "never felt this good in my whole life." They really have some good stuff in those cronk hauses.
Yep, the Camaro was one of the cars that survived the crash requirements and still looked good. Consider the biggest sales year for the generation was in the later 70s even. But I often wondered how a 73 Z28 would respond with only a head change? I know a set of big valve 64cc hump heads...
Yep, the hydraulic pressure goes somewhere to a dead head regardless of the prop. valve. Leaking back through or air getting into the system somewhere.
