Oh I've read a whole lot off Chads verbiage on yellow bullet, he absolutely detests AFR heads, and I really don't agree with him on that point at all. I'm sure he makes some good stuff, but as always it comes down to what you get for the dollar spent. He has always had a problem with what AFR advertises for their flow numbers but insists his are right on the money, he came very close to being sued by AFR for some of the statements he made. Now I'm not saying his heads aren't good because he has a lot of people that use his stuff and say they are very good. The problem I have is for me to get a pair of the air wolf 220 heads with the same parts as my AFR heads that I have now (Pac springs, .210 intake valves) it would cost me $1230 more than what I paid for the AFR heads and if you use the advertised flow numbers at .600 lift A W is 320 and the AFR is 312 that's an awful lot to pay for 8 more cfm of flow (even if the AFR flow numbers were way off and they are not). I'd much rather take that 1200 and spend it having my heads worked on. We have some real good head guys around here. But I'm sure what my stubborn a$$ will do is put the heads on the new build as is and see how it shakes out. But please keep the suggestions and opinions coming.

I really don't see a problem with using the 220's on a 421. Everyone has a budget to try to stick to. I think the 220's will get you to your goal. Have a custom cam built to what you have. A good set of heads with the wrong cam will be no better than a set of heads that are not as good, but have the right cam. That combo will make it's power at a lower RPM which is good for longevity! Gear it & converter it correctly & I think you'll be where you want to be.

Yep that's pretty much my plan but I always like hearing other peoples ideas on it, sometimes you come up with things that you just wouldn't have considered. The cam being custom ground is a very good idea, I've been learning to take the guys who build the stuffs advise on things, I did this with the converter I use now and the guy absolutely nailed it. He wanted all my info on the truck and I gave it to him and all he said was, I'll make you what you need, and man he sure did. So I will have no problem listening to a cam company for a custom grind cam, I like Lunati cams and valve train parts, I know the vast majority of people go with Comp but I've always had good results with Lunati pieces.

I just bought a set of used Canfield 310's from a local machine shop fresh & ready to go. Got flow sheets & port volumes on them, so I know exactly what they are. They should be a good head to put on the 461 in my Camaro. Never had a set of aluminum heads on any motor in this car, so I'm looking forward to the results. My cam & intake may not be optimal for these heads, but I'm certainly going to find out.

May have to wind up with a custom cam & different intake. This is what I look forward to finding out. I'd like to see just what I can get out of a 461 that is basically worthless in today's BBC world!  |

I would like to see just what I can get out of my 461" BBOlds its got a ton of torque and Revs like a beast. Rocket done a awesome job on this motor whrn they built it. Gotta just get my timing set to the right jetting. I got good parts in the car. Big Magna fuel 500 pump, big Magna fuel regulator 12an line from cell thru a spin on stainless filter then 12an to the pump with another filter. Then 10an to the earls inline stainless filter at the base of my Magna fuel Regulator. Then 8an out each side of the regulator to the bowls on the 1050 Dominator that Justus built. Got a Msd 7al -2plus with a built in 2 step, Msd Hvc Coil Msd Pro billet Distributor. Got a fresh TH 400 all new everything new hughes rev manual valve body and Trans Brake aerospace brakes all 4 corners 32x 14.5 rear Hoosiers car only weighs 2950lbs full of fuel. So it should step up and get with it. Oh yea has a 4.30 pro gear full spool big studded Moser axles set on Kill just hope it will run good. I know it goes fast enough to make me Giggle thats Cool!!!

Now that's what I like to hear..........some real car talk.......Somewhere down the road sometime I WILL do a big block car!!!! I've seen your car John and it's a beauty for sure. I'm using the MSD 6AL-2 programmable for my ignition, it makes it real easy to lock the distributor out where you want it like you were talking about in your other thread John. I run mine locked out at 36 degrees, the cool thing is that I can just connect my laptop to it and set a retard curve for it however I want to. So for me I drop it down to 26 on the start up and then bring it gradually up to 36 at 2000 rpm which is what I launch at. Triplenickle what year Camaro do you run??

If you go to the general board, there's a thread called reader's rides ( 3rd thread down). It's on page 8. You & BigD need to post some pics of your rides!

I want to say a coupe of things, first the truck 12 bolt rear is good enough to add a spool and a set of 4.56 gears and mosier axels with at least 33 splines and then you will have a good rear that will hold up to 1000 HP, next I would use the heads that you have on a 415-421 CI engine with a stock 400 block, I have built a 415 for a friend and its in a 66 chevy 2 with the same heads you have and a solid roller on alky, a PG tranny and 500 gears and it runs 590's all day long, with a stock block and crank, its got about 500 passes on it now and still running strong so with that said your truck and your heads and intake and a 415 CI bottom end, 12 to 1 compression, solid roller, 5000 stall, T-400 with a brake,and 456 gears on E85 fuel it will run 630's to 640's all day long and thats 990's to 10.00's in the 1/4 mile

Man that is some seriously encouraging news there BB, and I needed that after getting up this morning at 6:30 and finding one of my aquariums leaking in my rear bedroom and bathroom nice mess, it's taken care of now. Man I have to digest this info, it will like you said earlier save me a lot of coin!!!!!! As for the stock block 2 bolt high nickel block or should I look for a good 4 bolt block, I'm amazed that the stock crank will hold up to that. I have all kinds of time to find the block and crank too. Thanks Bud!!!!!

Ok BB I'm doing some thinking on this, one question I have is this. how do you come up with a 415 using the stock 3.75" stroke crank? Even bored +.030 using a stock crank it works out to a 406. Now if a 3.875" crank is used at the stock bore of 4.125 you get 415.

Now if a 3.875" crank is used at the stock bore of 4.125 you get 415. the block was .020 over and the crank was offset ground .100 to make it 3.850 and we used small journal rods but now you can but the kit with a better crank this was some old school stuff he had and I just fixed it ans made it better, I would use a 2 bolt high nickel block and a stroker kit from OHIO crank and get 418-421, the block will handle 650 HP with main studs. |

Ok cool, this is sounding pretty good, there is a block and crank right now near me but I don't believe this one to be a high nickel block ( detroit.craigslist.org/okl/pts/5056795194.html ) also what length rods did you use on that build 5.7" or 6" and did you have to do any clearancing on the block at all?? |
