iv'e sent my specs to comp and lunati no replys so i'll ask those here,combo is 500" indy 440-1 otb 12to1 comp,indy single plane 4150 flange,4500 stall power-gide,4.56 gear,14x32 m/ts,3000lbs race wt,would like to stay around 7200 max rpm,1.5 rockers.this is a foot-brake car.thanks,sam.i have 1000cfm hp or 1050 dom for carbs. forgot looking at solid flat tappet.

FWIW (just another opinion to throw into the mix), I'd try something like this, only ground on 110 LSA and installed on 106 ICL.

EDIT: On second thought, given the 2-speed trans, it might actually work better w/ the 108 LSA that linked cam is on.

the smallest i'd even consider would be a mid to high 270's@.05 also, put the dominator on it.

I missed the otb comment...if your not porting them at all then yeah, I'd run 276/280 @.050 still on a 110lca though.
Are the heads untouched?

It all depends on what you let me get away with power wise...!!
More power, how's that!

Racer Brown STX-22. 276-276 dur and .590-.590 lift. 106sep and in at 102*
Would be even better with 1.6 RAR. I know a 2500lb Vette with a 500" Indy -1 headed BB Mopar that has gone 8.50s with the smaller STX-21 272x.560 with 1.5 rockers. The STX-22 with 1.6 RAR in my 418c.i. production headed sb mopar has gone 9.68 at 135+ at 3050lbs. Must mention the one in my Demon was bought off eBay for $50 never used and was made in 1970. They are still making them the same. Call Jim at Racer Brown. 410-866-7660

nick at compu-flow checked them over a corrected valve sealing issues,also up graded retainers and springs to match the comp cam he speced,it lasted 2 passes,4 wiped lobes.so new block,pistons,all machine work and ready to try this again,i have the power-glide now ,727 before.thanks for the info guys.

Sam, here's the Scott Brown solid I'm using:
.648/.640 274/280 112 lobe sep, 108 intake centerline

Here are the specs on 440Jim's Scott Brown cam that got him in the mid 9s
.623/.600 272/280 112 lobe sep

Here are the specs on 440Jim's Comp cam that he's running now: MM-305S-10
.650/.650 279/287 110 lobe sep

Here's that big Ray Barton that I have if your interested (only has 25 passes on it, with lifters, already broken in but may be a little big):
.639/.640 283/284 108 lob sep, 104 int centerline

I'd also recommend using the newer lifters with the EDM hole in them to provide some extra insurance against lobes going flat. I got mine from Hughes, I know Jim runs EDM lifters as well.

If you loosen the converter to 5500 plus rpm, you can go a lot bigger than you might think. I just found an old time slip that showed my car with a 499 lowdeck, 440-1 with bowl porting only, alky injected 12.5/1 compression at 3000Lbs went 143.3 mph, 9.340 with a horrible 1.366 60 ft. I had an ultrdyne roller in it, 283 @ .050 int, 290 @ .050 exh, 108 lsa . Corrected altitude for that run was 1650 ft. Shifting at 6800 rpm.

thanks wade,i was going to call you to see what specs were on yours.i just would like to be around 10.0 like your car.i'm guessing racer brown and scott brown are the same place?

Nope, Racer Brown is "old School" been around for many years and I don't mean any disrespect by the "old school" comment. His cams are very proven and many guys love his cam profiles. I've never ran one but I've heard a lot of people speak highly of them.

Scott Brown is Straight Line Performance:
http://www.buyracingparts.com/
He's a younger guy, and very very well respected cam spec and builder for a lot of people here on Moparts. A year or so ago that's about all any one was running. He's a mopar guys and has a lot of knowledge on Mopars. Here is his number (616-499-6223) , you can tell him about your car and motor and he will send you his recommendation for a cam. I've ran about 4 of his cams, great guy, great personal service, he's always gone out of his way for me.

He had an opportunity to go work for a company doing some really leading edge motorsports stuff so we lost his focus for about a year but he was still doing cams just wasn't doing much advertising. But that company went under so he back working for himself now for well over a year now.

If you call him, be sure and ask him about lifter and spring recommendations, hopefully your spring will work since they don't have but 20mins of run time on them.

thanks for all the replys,called scott brown and he hooked me up for my combo,which uses specs close to what was recomended here ,thaks again,sam.
