Planning a new 2165cc for my 67, some camshaft ideas
alex d:
So originally I wanted to do a simple period warm up of the stock 1500 but ended up running into too-good-to-pass deals on big parts so somehow the idea morphed into a stroker with IDAs ;D
Stuff I have:
-Stock late 70s AS21 case, it was linebored in the 90s and never used again, needs bored for 94s, stroke clearancing, drilling for full flow, etc.
-78mm revmaster crank (chevy journal) and H-beam rods (stock length)
-Denham big oval port welded heads, 42x37.5mm valves, relocated plugs, 45cc chambers, these heads were freshly done and never used, they come with match ported intakes for IDFs, which I'm not planning to use
-almost new IDAs with 37mm chokes, choice of short or long intakes (would need to be matched to the heads, the short ones might need welding to reach the big ports, have not checked yet)
This is not a daily driver, but I don't need a racecar engine either. Some sporty "camminess" would be nice, at the same time I'm not interested in changing valve springs yearly. Also note that the 113 heads don't have intake guide bosses, so I'm concerned about not going too wild with valve lift.
I will be using stock ratio gearbox (4.125:1 )so I was thinking something around the lines of an Engle FK10 or maybe a Webcam 86b+6 (extra duration custom order), SLR XR310, any other ideas? I could probably just run a 86c and run 12s all day, but I'd rather have something less aggressive for the valvetrain, and a Fk8 seems almost boring for a stroker
also the 45cc chambers mean I'll be dishing pistons to get a reasonable compression ratio, how much can the AA cast pistons be dished safely?

He didn't have to wait long at all. Jeff just sold him somebody elses heads who'd already paid in full, waited 5 years and has given up on them. ;D :D ;D

I bought the heads from someone else that already had had them for quite a while and decided to not use them
now we can go back to discuss engines ;D
