Thanks for the reply Travis.
I know there is nothing wrong with todays dished pistons and If I cant get my CR to ten or just below it I will go with them. But I still associate the dished pistons with the end of the musclecar era when Chevy went from flat tops and domes to dished pistons around 72 or 73 (no I am not that old.)
I know flat top pistons come with different sized valve reliefs. The pistons I was looking at were flat tops with 7cc valve reliefs. With a 72 cc combustion chamber on the head, what is my compression going to be? How much would it change with a 74cc head?
How much more of a cam do you guys think I can get away with before I lose streetability. I dont mind the RPM band kicking in a little higher but keep in mind right now I have 3.08 gear with a muncie M20.
What I don't want now is an engine like I had back in my 68 SS in the early 80's. (teenage gearhead days) 350cu in 030 over, 11cc domes about (12:1 CR), Weind single plane 800-850 holley DP etc. I cant remember the cam specs but the power band was around 2700-6500+ RPM. It had 3.55 rear gears with a M22. The launch in my vert is about the same 7.76 vs 7.81 then but I am running shorter tires now 26.1" now, 27.5" then.
My point is I just remember what a pain it was driving in stop and go traffic, but man would that thing scream from 20mph on up. I think I could get away with something a little closer to that (the cam,not the CR),now if I had 3.73 or 4.11's with the m20, but I dont want to be turning 3000+ on the highway either. I still love the kind of performance of that 68 (very fond memories), but now I just want something with better street manners, for when I am stuck in beach traffic during the summer, and cant get the thing out of 1st gear.
Later I'll get a TKO, change the rear gears, and then I'll think about a cam upgrade.
Al, what is involved in a hydraulic roller retro fit and are there any durability issues with the retro fit?
Eric, Who is an online vendor for the SRP pistons so I can do some research on them?
Again, thanks for your time and help.
P.S. I just thought of something on the cam I know you can use more lift and duration on a 350 as compared to a 327, so I guess that also holds true that you could get away using a cam with more lift and duration on a 383 as compared to a 350. Is that correct?
