Yep, not really worth milling stock sb mopar open chamber heads more than about .030 max. Even NA.. This is just my opinion of course…

Nope, this is what I have heard from guys going really fast with stock parts .

i wouldn't go to far milling the open chamber X or J heads, i hear if you don't have at least .100 between the "quench" area and the piston if effects the flame travel..

20 psi at hot idle is fine

Probably around 425 hp without knowing compression and head flow numbers. IF you built the car correctly then you put a higher stall converter in if it’s an auto, AND a performance oriented gear ratio which would allow you to use a 750/800/or even a 950hp carb for even more horsepower and the...

Heavily worked 71 manifold

Factory underrated all 340’s at 275hp the 4 speed cam, the t-quad with the better intake in 71, AVS 340’s around 300hp, 71 340’s closer to 315 and 6 pack a little more. NHRA pegged the actual HP back in the day. 340’s and Hemis were underrated, 383, 440, and 440 + 6 were a lot closer.

And the 71 340 with the 800 cfm t-quad makes more HP than the 625 AVS, OH…. and the 340’s with the 1350 cfm Holley 6 pack ( 950 actual cfm) make even a little more !!

I’m going to make you an offer you can’t refuse.. Swing by and pick up my 750 Holley competition #0-937 9 dp with annular boosters and choke horn milled. You can try it out this summer.

Yes. I’m going to shot for about 89% of the seat width.

Well I think this is about done!! I’m running a 6 pack intake so if I can get these to go near 240cfm at 500/550 lift with a 2.02 valve I’ll be happy. Now to start the other 7 cyl.

I have a dead head now but purchased a bypass

Do bypass regulators bleed off fuel pressure when the engine and electric pump is off? Reason I ask is I have a heat soak restart issue and I know it will help cool fuel make it to the carb if it’s plumbed after the carb but if it doesn’t release pressure in the line at shut down i may be...

Yep, I’d have a pair of those rectangle chunks of aluminum on my motor especially if I wasn’t going for stock appearing !

A little closer, man is this labor intensive.
