I just want to share my excitement with all of ya's..... As you know from my signature, I've been racing a 306" - while on the engine stand is my 460" mill that is slowly, safely, being stretched to a meager 501".  Well today arrived my #2965 Victor 460 intake which is outfitted with the 4500 flange. After looking at 289/302 intakes, WOW!!! NOW THAT'S A CARB FLANGE, AND DEMS ARE SOME BIG INTAKE PORTS!!    WAY TOO Ryan  ------------------

If this 501 is for race use and your are using a CJ style intake port, it would be a good idea to port that intake to match the heads. It came highly recommended to me in the 385 forum. Dave Mclain flow tested a set of heads without manifold at 369cfm, when he bolted on the intake straight from the box it flowed 300cfm. After some port matching(only the first 2in of the runner) flow picked up to 360cfm bolted to the heads. Now i dont know about you but that sounds like horsepower to me.

Fred,
I can hardly wait to feel the pull!
Thanks for the tips, Jed & JS !
Yep, the fat block is destined for drag racing use and I do plan to port-match this intake to the heads. I'm still saving $$ & watching the classifieds for a pair of Edelbrock RPM 460 heads. Of course, if I come across a deal on the new SCJ aluminum heads, I'd snag them up in a hoofbeat!

....which is nearly TWICE the 1.05 X 1.88 port area of a typical 289/302/351W intake/head!

The intake is good, but will have a pretty bad port mismatch with any head you choose. It's designed like that on purpose. It's an in-between size. It's a larger port than a DOVE type stock head. But not so large that the DOVE head can't be opened up to match the intake. It's smaller than a CJ port of the D00E or aftermarket heads. In that case you open up the intake and leave the head alone. The mismatch will not be even all the way around. It's close going up the side and top/bottom. Where the mistatch will be is like at 10 and 4 o'clock or 8 and 2, depending on the port. I had to open my intake up to match the Blue Thunder heads. I also cut the cloverleaf out of the top since I was using injection and all the flow in the plenum is dry flow. For a carb keep the cloverleaf. You can also get a cloverleaf carb spacer to match. Later,

Yeah I agree with Dave - I had my manifold and heads ported by someone who knows what he is doing. Manifold port matched to the heads, the plenum now resembles the cloverleaf of the 4500 flange with 2 of 1" spacers making a transition to the carb. It was money well spent! Nothing wrong with Performer RPM heads! There was a fella last year with a low compression hyd roller 514 running highish 10s - first time out (engine builder was same fellow that ported our stuff). ------------------

Thanks Dave & Fred for the additional thoughts & advice! I suspect the use of 1 or 2 of the 1" spacers would be helpful, it will depend on whether or not I have the hood scoop clearance... Good to hear of someone running Edel RPM heads and happy with them! My plans for the 501" now is 12/1 CR, Edel heads (not sure about valve sizes) with a 265 dur & 720 lift solid roller cam, Crites headers & mounts. However, I also need to upgrade the car with a rollbar, a McLeod's soft-loc and a Jerico before the fat block goes in. Many $$$$$ more!
I'm hoping for mid 10s..... As I get closer, I'll bug you guys more for some of your expert advice! Ryan ------------------

A friend of mine Rich kent runs the edelbrock headso n his Pinto and does quite well with them. I had to port match the Wieand tunnel ram to my Motorsport SCJ heads. I think it helped. JS

Ryan, Im about finished with my 67FB and as soon as i get it to the track i will show some pics and post the results. I am runnin the Edelbrock CJ head with some exhaust port cleanup on a 501. I couldnt afford the roller at the time so i used a Comp solid flat tappet with about 650 lift and I also have about 12:1 compression. Im using the Victor intake and Dominator carb. Im only a set of headers short from completing it. They are from Crites. A word of advice. Order them waaaaayyyy ahead of time. I ordered mine a month ago and they still have not arrived and they told me they have no clue when i should expect them either. Ill let you know how it goes.

JS,
Those SCJ heads are the newer castings with the 'centered' valve placement, correct? How are you liking them thus far?
What headers/mounts did you use in your '69?
Jed,
I'm sure we'd all like to see some pics of your 67FB with your 501! I'm sure that Comp solid flat tappet with about 650 lift will still let 'er snort!
What size Dominator did you bolt on?
I was figuring on a 1050....JS & Jed:
Are either of you guys able to stay under the hood or do you have to cut it & use a tall hood scoop to allow adequate clearance above the carb?

Ryan, No they are the old style SCJ aluminum heads. I have no plans to update them. They seem to hold their own agaisnt the folks I run with.
The mounts = front motor plate and a mid plate. Fabricated headers from a STAHL header weld up kit. Over the frame/side exit style
I run a Wieand Tunnel Ram with an alky injected hat, so no it is not all under the hood.
sounds like you and Jed have a similar set up.
Good Luck!

Later last night I remembered that you ran a serious alky setup & likely used motor plates.  Nevertheless, thanks for the reply and Good Luck to yourself! Ryan

Sorry Ryan, I was not able to stay under the stock hood. My Dominator(1050) sits about an inch or so inside the hood scoop. as a matter of fact so does a little bit of the spark plug wires and cap to my surprise. I used the MSD billet, but a probillet or low profile would have fit better but i had already used this one with my cleveland. I plan on switching to a 3 or 4 inch cowl hood next year. They look really nice on the fastbacks. I need some fiberglass anyway, this thing is a tank. I figure it will weigh around 3300 with me in it. These things definately weight more than they look. Feel free to ask questions, I love talking about this stuff.

I agree, I also think the cowl hoods look good on the '69/'70 FBs....Just take a look at Kid Vishus' car! Thanks for the invite on questions...and I will take you up on your offer, as my project progresses........... Ryan

Thats some pretty darn big ports. I will measure up the ports on my A460 single plane tomorrow and we can see how they compare. I am interested because I think I heard that the Victor/CJ setup actually have larger ports than the A460 heads, its just that they are raised way up on the A460, for better flow.------------------
