Looks like Cotten's 383" get them? Just great, it already had 35 hp taken off.

Looks like it is only 30 horsepower off with the heads.

Hi Ed, yeah you're right, the 383s have a sweet deal right now but, with the exception of the Bortman wagon thing and the 383/343, the 383s were completely uncompetitive for 42 years, mostly because of the small carb. You either ran a Hemi, a Max or a Six Pak car, not easy for the average racer to afford or put together, and the motor that was the most plentiful and cheap couldn't even be considered. Every dog has it's day and I guess ours has finally come. If these heads turn out to be worth more than 5 HP and I think they will, NHRA wont turn their heads like they did with the new cars, they'll slam us hard.

I think that 60917 might be a misprint. I don't see that number in the Edlebrock site, but 60919 is there and it is a 84 cc bare head which might be right. Course you gotta install the small valves 2.08/1.74 3/8 stem, but I guess you can get the cc's down to 79.5. I think the rule is the heads are allowed, but the valves, chamber etc gotta be right. Travis, I know you read this, how about a clarification here or maybe Tuesday Tech. Also the Eddys have angled plugs, so they might not clear your headers, but the Mopar 452A has straight plug and will fit. The rest of the head is the same, assuming the 60919 is the head intended. Calling Larry Hill----Calling Larry Hill----Soupup the pink car so you won't have time to complain about the new cars. Showtime

Somebody tell me how this works: if I have a 1964 383 with closed chambered heads and now I can run the alum. 452's.......how do I get my compression back without having the NHRA changing the piston choice for the closed chambered motors?

We have the Edel. Heads on a bunch for our Bracket Stuff.......Routinely down to 75 CC. The spec is 73 on the Early Head I think and should be
no sweat to make them that Jim. I think early 383 are neg deck flattop so should be fine on piston to head. Later ones (68-69) with positive deck might have to give up a little on deck or run thicker than spec Gasket...., but should be only 010-015 at most. Piston to valve might be a little tuff with no valve relief (As in Sink your valves a bunch).....If you need more info Jim PM me
I know the fix.

PS: Doing much Better!!
