Well if your dead set on stock stroke and manifolds I'd try to get the same cam Bob K put in Scott McKenzie's car, not sure if that's his regular grind or something else...

Yep , i asked Bob for that info ; and hes gotta cam
for me , however theres a little bit of new technology
Out there since Scotties build, i think - i gotta be a touch more
Hp - im heavier than the fatA12 car. But thats the goal .

"noone is handing out buildsheets of how their running
Low 11's on a stock looking motor , and driving their cars on street."

What do you want to know? My engine meets all these criteria save for the exhaust manifolds.

IMHO your best bet for the most hp on the cheap is offset the stock crank to 3.90 for 470 cubes. You said you didn't want to stroke it, but that is a great combo for a stock size port head! The extra stroke will help with a heavy car is a street strip type of setup because the motor will spend a lot of time in the lower rpms of the first half of each gear. Paint the right set of aluminum heads for the look, get good quench of .040 with a reverse dome piston, 7.10 H beams to help with lightening the rotating assembly. ANDYF really liked the Mopar 528 mechanical cam with stock manifolds, so something real close if not that cam. Research where the best gains are on reworking those stock exhaust manifolds. No experience with them here, but I am thinking it might be possible to get some gains by opening up the outlet area and using the right sized pipe for the full exhaus5 system, plus the right CFM flowing mufflers, cross over, etc to keep every Hp you build into the motor.

Hey Andy, Amazing how the time goes so fast.. The car was a purpose built 11 sec stock stroke A12 for street and some track
duties.. I don't know the whole recipe But as stated in the article above it has 11.97 comp, mild head work on 906's, good
internals and 60 over.. The cam is Bob's own not the usual grind.. The engine was never on a dyno I would estimate 525 to 535 hp.. My best et to date is 11.61@ 117.96 with a 172 sixty
on a stock bias ply tire and a 2600 converter..
Good luck with the build.. Scott..

I would run the aluminum 6 pack intake though

Andy, BTW This Last F.A.S.T. race at MIR young Brian with his
71 challenger 493 [pump gas]six pack, Dwayne porter heads.. Was running
low 11.70's almost 119 mph 182 sixty with a four speed.. I would
think with better sixty's should go fifty's..

Hi Scott
I miss drinkin beer with you , we will soon.

So if you had to do it all over , what would you do a little different ?
Bob doesnt remember exactly how he made up your mill.

When I grow up , Im gonna have a car just like yours .

Bragging rights because you spent $1500 on a pair of iron heads that you could have duplicated for $1000 in aluminum?

Oh, well, if that floats your boat.....Better get one of those Purple Shaft cams!

R.

The cam you use on a 12:1 CR motor might be different than what you would use on a 10:1 CR motor. I would think how you manage the blowdown of the exhaust on a 12:1 motor would be a different than on a 10:1 motor, and would be especially sensitive on an exhaust manifold motor.

Scott, what do the heads flow, weight of the car, and the DA at Martin (?), if you don't mind my asking?

Nice running car!

Thanks

Andy, Just call Dwayne... One stop shopping

Its almost like you already know the answer but you want to hear how others would spend your money.

This!

Long time no see Andy.. I wouldn't do anything different.. Very reliable, fast enough for me... I didn't want to go the stroke
route.. Wanted to keep it as real as I can...

Weight around 3900, Head flow? little cleaning good valve job?
DA= 2500 to -200 It will run 12.00 to 11.61 113.00 mph to 118.00..
Thanks..

Yep , just a refresher course and its fun lettin other people spend
the imaginery money on imaginery things.
I Talked to Duane, he can do what I need , just hope the whole combo
gets good results.
-And it doesnt sound like a boatload of cash.
Cheaper to learn from others mistakes if their willin to share.

With the iron heads you may need to cap CR around 9.5:1. If you're married to those iron heads, be sure they're ported well. I would do a MP 528 solid cam, hp manifolds and call it a day. Great street car.

Not quite 500hp, but the 426" in the fury made 458hp on the IMM engine dyno with 9.6:1 pistons.
Brian's port and valve job on stealth heads.
EX275HL hydraulic cam, performer rpm intake and 770 street avenger carb.
If we'd have painted the intake and heads it would look stock. Well, except for the chromed M/T valve covers.

426 Dyno Pull

I guess you dont understand , it was like Scott said
keepin it real .
In the early 70's they didnt have all the new crap and
Cheap stroker kits .
They did ok with the stock stuff .
Used some ingenuity - Lightened creatively and ran 11's.
I dont want to bolt on aftermarket on a real car
- ill do that on a restomod or a daily cruiser.

If i find the extra cash , i might still stroke it , because its a lotta bang .
4000 dollar build goes to 8 fast .

I don't understand the need to bash anyone for using cast iron heads over aluminum, hell I know guys that are hotrodding flatheads. I Would not use the valves, springs etc. that come with the cheaper heads, buy them bear and put good parts in. I personally like being told you can't make power with a set of 915s and you need to have bla bla aluminum heads, only to come up with 620 tq and 645 hp from 3000 to 6500, a great street motor that has and will run to 7K.
To each his own.
