Hey Andy, do you have or know where I can get those raised-runner 23° iron heads that flow 400 cfm for my SBC ? My RR SBC heads only flow 355 cfm. The 14° heads flow 400+ cfm. And yes our early iron Hemi is over weight, but we are working on that. One of my RR SBC was at 16 1/2:1 compression, but now mostly because of bigger cams the compression is more like 15 1/2:1. And Park's 14° SBC motors were more like 14 1/2, running over one inch valve lift, and 10,500 rpm, at 6.76, 197 mph, Racing Comp Elim.
Now Robin, you are telling NHRA they are ignorant, planning on racing any NHRA events ? LOL. Are you saying it's not right anyone can not run after market hemi heads like the SBC'S ? 1'st of all Hemi heads can run bigger valves than SBC because of the camber shapes. Don't get me wrong I'm not Happy about the Parks Hemi heads, but they did everything that NHRA asked them to do to get their heads approved for "replacement Hemi heads", as it says in the NHRA approval letter I saw at the March Meet. The NHRA guidelines they received when they 1'st asked was the new Hemi heads could not be any higher, longer, or valve angles could not be more or less than 3° from OE, as in the rule book for B/ND. I'm not trying to defend NHRA approval but maybe the water jacket issue is they have have approved lots of billet alum heads with no water jackets. I had one A/ND & B/ND racer call me after the Gainsville meeting and said he thought NHRA should have changed the rule book, but if they approved the heads for Hemi replacement, maybe that means the after market heads are like OE heads, just like the after market you and I run on our SBC's ? Keep in mind NHRA had the sample heads to look at and approve, it's not like they never saw them. I feel better about keeping JF class alive when Frank said they are only racing this year in JF Heritage, and has said they really don't want to hurt them self by changing the "B" handi cap, or screw-up our west coast deal. BTW, Parks will not show up at any SWJFA races, because their motor is 421 ci, which is legal for B/ND, since some Comp racer talked NHRA into increasing the ci limit from 410 to 430, and SWJFA, has kept it at 410.
There has been lots of talk about the N&P heads, that took them 10 years to build and get approved, but you should know they did their own design and machining, besides "thinking outside the box", and I've thought maybe it's time to go to real OEM heads. But of course that would mean we would only have one legal race car, ours with our early Hemi. But if you think that's a great idea, just send us the money to convert all of the other 8 teams that raced the MM to convert their motors to OEM part numbers. Or if that seems to much, then after market OE style heads like SWJFA might work better, then just just enough money to convert just 7 teams stuff. So lets say we go to the non raised runner SBC heads like you, that flow about 300 cfm, then what do we do with our Hemi that flows 370 cfm, it just doesn't seem fair to let the hemi out flow the SBC's. does it ?
Now, it does seem the N & P hemi heads should be "A" class, were the rule book seems to allow any valve angle and 3 1/8" injectors, but their valve angle is hemi OE, and they are using 2 7/8 injectors, so what makes them "A" heads ?
As far as the money issue, yes Comp racers have been spending $70k+ on complete race engines for years, but NONE of our guys that race JF Heritage have spent anywhere near that. We are budget racers too, and asking our racers to spend more money so we all can race in the same class and heads-up is not in the cards. At the March Meet, we had 3 "A", 5 "B" and 1 "C" cars. One "A" car broke so we had a full 8 car field. We will have one more "C" team joining us this year and another "A" car along with another hemi team. Matter-a-fact I know a Comp racer that over the winter spent $130 k on a Pro Stock motor to race in A/AP, and picked up 100 extra HP.
Maybe when the new JrFuel class was formed in the early 80's they should have really spelled out the rules, so only OEM heads would be allowed, and no grey area about after market heads, much less the Paul's Buick heads, but the rules were not that spelled out.
I wonder if some team made their own cast iron non-raised runner SBC heads and raced SWJFA, with OE head bolts, no plastic, and no lifter relocated, how that would fly ?
And what about Ford heads, they can be made to flow close to the 14° SBC heads. SWJFA allows iron Ford heads right ?
I hope this clears up some questions, and I'm not just stirring the pot !
