Mopar Got Heads
 

Thank Goodness

Re: Mopar Got Heads
 

Which engines, Jeff?

Re: Mopar Got Heads
 

????... BTW, Did Scott get your new goodies from us today?

Re: Mopar Got Heads
 

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

Re: Mopar Got Heads
 

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

Re: Mopar Got 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.

Re: Mopar Got Heads
 

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

Re: Mopar Got Heads
 

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?

Re: Mopar Got Heads
 

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!!

Re: Mopar Got Heads
 

Paul, if you can't be deadly fast with factory heads after 35 hp has been taken off, you need to find something else to do.

Re: Mopar Got Heads
 

Jeff.....the Edelbrock 60917 must be correct because they are listed in Summit's website and they describe them as having straight plugs.....

Re: Mopar Got Heads
 

60917 is the correct number for the Edelbrock heads and they have straight plugs as OEM.

Thanks NHRA!!

Re: Mopar Got Heads
 

Has Eddy made any yet? We asked them (we are a dealer) and they said no.

Re: Mopar Got Heads
 

Edelbrock made the changes to the performer casting to suit NHRA. They will be straight plug And closed chamber. With the correct valve you can bring them to 69 cc with no problem. They will accommodate all of the combos with ease.

I have an order for 10 pairs,Edelbrock is going to let me know by friday as to when they will start production, i wil let you guys know what they say.

Re: Mopar Got Heads
 

This should get interesting, any idea what the 60917 casting is going to cost Erik?

Re: Mopar Got Heads
 

The ED castings are around the same as we were paying for the Iron 287 head.

Re: Mopar Got Heads
 

ouch! but your right I should find something else to do lol

Re: Mopar Got Heads
 

But, you are! Now you get aluminium heads at only 5 hp? LOL

Re: Mopar Got Heads
 

Thanks good Comedy HAHAHAH!

Re: Mopar Got Heads
 

It looks like they will be legal for the 1964 MW engines as well as they are listed in the 1964 Plymouth classification guide. I didn't see them listed in the 1964 or 1969 Engine Blueprint specs for Chrysler engines. Maybe NHRA hasn't updated the engine specs yet to match the classification guides?

I would think the Edelbrock Victor head with MW ports would be a better match for the MW head replacement than the RPM head.

Re: Mopar Got Heads
 

Mike, I know you didn't knock the hp rating down, nor make those heads legal. I don't blame you for picking a soft combo either. Anybody would. Hope it didn't sound like I was blaming you. If those heads flow anything like the Edelbrock Pontiac's that 55 lbs you have to add won't bother you one bit. I didn't know your engine hp had been lowered until I got Nitro Joe's book. I apologize if I made you mad. You and Paula are two of my favorite people. Sorry.

Re: Mopar Got Heads
 

Gee Ed, I ain't one of your favorite people?

Re: Mopar Got Heads
 

Yes Jeff, you are. Your a lot of fun.

I've known Mike and Paula since Mike was driving the first Duster as a daily driver.
Really fine people.

Re: Mopar Got Heads
 

Ed they will always be some mopar lurking in the shadows looking for heads

Re: Mopar Got Heads
 

Yeah, probably with you wrenching on it. LOL
