Cast iron head porter suggestions please.
 
I see that SD Performance no longer ports cast iron heads per their website.

So.. who would you all recommend??

I've got a set of 12s and a set of 62s that I'd like done.

Paul C at Carter Racing may be one place to check. He may or may not be porting iron heads.

Another one that was part of an engine build I got involved in is Dan Barton. He ported a set of 72 455HO heads that I had Paul C rebuild and flow test. The port work on those were excellent. Don't know if Dan is still porting iron heads these days or not.

Iron has seemed to fall out of favor with most head porters when you have a market flooded with aluminum offerings these days.

Marty Warden in Charlotte NC area did a set of 670s for me

JBP ports iron heads but it looks like you buy directly with option to send in cores. Would be worth asking if they'll just perform the work on yours: https://butlerperformance.com/i-2445...tegory:1234782

Also consider Paul Knippen who posts here. He is very adept at porting cylinder heads and has a flow bench. His cell is 630-400-4441

He has the highest flowing set of Pontiac iron heads on earth. So yeah, Jim.
How many other guys run a 8 second NA Pontiac with D ports ?

Jim is a bad dude, but I don't believe he's been 8s or even knocking on the door of 8s

Paul Knippen knows how to make power

Bill Eveland 01-26-2023 02:28 PM
Did you try Automotive machine in Pekin? Alan left whats left of Mullvains or weddle and works over there now I believe. Id never stop foot in that shop again. they tried screwing me over and everyone else apparently

What I have on this list is 9.48 @ 142.87 @ #3385

If anyone has any faster runs for Jim please forward me that information.

I am thinking about a thread or post from not too long ago. Had a sheet metal intake, think car was blue and his son and new bride was in the pic.
He did do the 320cfm pair of 48s that made 871 HP. Not sure if it had any power adder but you would think it could have.

Why can't you just say sorry i was wrong??

Not close to 8s. Jim is great, no need to embellish what he's done.

He did do this. 871 HP out of a stock block is pretty good.

slowbird, I am simply thinking out loud , trying to figure who has done it. It has been done, iron heads in the 8s.
Might have taken a light car, so what. The Butlers had some guy do it years ago with D ports;
Dan had a guy who could run 8.90s with his RAIVs a long time ago too.
But for some reason you want me to admit I am wrong.

Jim has been 9.39 with 96s. That a pump gas head.
8s are possible with smaller chamber, more CR and lighten the car up. Or real close to it.

You are wrong, you said Jim has ran 8s, he hasn't. I agree iron heads can go 8s, heck Marty ran 7s and so has Jim Y but that's not what you said.
Jim's 9.39 was not on pump gas and was not low compression. You need to check your "facts" better.

joes455 01-27-2023 08:03 AM
Jim is from pics on his site does great work

joes455 01-27-2023 08:16 AM
I also wanted to add getting good low lift flow #s 265 @500 is fairly easy with little work on the short turn.After 500 or right when ,and it will #s will fall off by 20-30.The talent of porting the d port is getting that 265 back and biting at the str to extend that to 300 or 325.I wonder if he is using or any other porter of these heads a 2.19 valve?Cast heads are tough, messy,hazardous to the lungs,kills burrs,takes time and porters don't get paid enough

You indirectly implied Jim ran 8's in the quarter mile.

You backed up your false statement, but implied maybe it was 8's with a power adder. Also blaming your incorrect post on brain fog.

Now you say you never made an incorrect statement, because once somebody does run eights your false statement will become factual.

Now your saying other guys (but not the guy you said) ran in the eights, so your false statement should really be considered accurate.... even though it was false.

Now you are fantasizing about what someone else should do so you don't have to own the false post you made.

^^^ THIS! Wouldn't it just be easier to own that you were wrong about Jim running eights.... Then you could apply all that waisted time towards getting your Hot Rod running so you don't miss another season of racing.... Just saying.

chiefbigb 01-28-2023 01:02 PM
It's pretty easy to get around 250 at .550 out of iron heads. I have ported many sets. Lower lift numbers are strong and they make good power. I have a set of 48 I did years ago that hit a bit over 270 and that was ten times the work for 10 percent more flow. The port needs to match the combination.

Pontiac Derek 01-29-2023 12:47 AM
Jim Robertson or Dan Barton 100%

8s are possible with smaller chamber, more CR and lighten the car up. Or real close to it.
Fact # 1: The Butlers DID have a guy who could give you a 262-265 cfm head (head after head). With that 265 cfm head the Butlers could run very good times (for that period), BUT THE BUTLERS ALSO RAN HIDDEN NOS ON THEIR ENGINES. So the Rodney/David Butler 265 cfm heads that ran in the 8s ran there because of several reasons. Spray, light weight, good cast iron heads, lots of track time.

Fact #2: The man has since passed on (years ago).

Aluminum Heads from Edelbrock was Jim Butler's solution to not having the cast iron employee's porting skills available.

Few know more than bits and pieces of what really occurred in the early Pontiac/ Butler
Days. I believe Dan Whitmore was another guy with a lot of talent, just like Butler's guy, AND Barney Mahovitz, AND Mr Robertson.

Hope I spelled Barney's last name correctly.

No Sir. Just trying to keep PY from turning into PZ. Also don't mind giving you tips on time management. That's what this site is for. Pontiac folks helping Pontiac folks.

Hope you get the Hot Rod done. Two missed season's is a percentage of time lost.

I remember when Whitmore's top guy was going up against Rodney Butler in a final round. He was suspicious because the Butlers kept pulling their car into the trailer to work on it.... He opened the door to the trailer and found the "hidden" nitrous system.

Round ports run faster than d-ports "for a reason".
