521, P-51 heads. Cam/intake/carb advice

Hey! First time posting and I have a few questions.
Here is what I know:

1. Intended use - Street/Strip cruiser

2. Vehicle info (weight/gearing/trans) - 66 f100 short bed, ~3700lbs, 3.90, C6 with 3200-3500 stall

3. Fuel desired to use - Pump gas, best we have in Midland Tx is 91 octane

4. Parts you already have - 521 FRPP stroker kit - 4.390 bore/4.30 stroke, 28cc dish pistons. Block is zero decked. Kaase P-51 heads. I have not ordered head gaskets yet so compression can be between 10.5:1 to 11:1. 1.73 rockers.

5. Proposed budget - $3k for all gaskets, arp bolts, oil pump, intake, cam and carburetor.


I called comp cams today about a cam. They recommended a custom grind. Here are the specs:
lift .761/.762
adv duration - 288/300
@50 - 260/268
lobe separation - 112
center line - 108/116

Will this cam work well for my wants and be fun on the street?
What intake and carb do you recommend with this setup? I was originally wanting EFI, but it seems most companies miss that 650-800hp range for their EFI units. I'm ok with a carb, just thought EFI might be nice.

Thanks,
Wesley

Will it work well YES, want to make it better call KAASE............none better IMO!!

Try the new stealth sniper 4500 efi carb with a mafia intake.

Looks like a fun build.

Or get in touch with Scott Johnston aka The Mad Porter. He set me up with a set up very similar to yours and it was exactly what I wanted.

Cool

How much street time is this combo going to see?

Aggressive solid roller lobes and the required spring pressures are hell on lifters. A quality bushed roller lifter is a great idea.

It will probably only see street time. Friday night dinners and Saturday car shows/meets. I'm open to suggestions!

Is the rotating assembly new enough that the valve reliefs in the pistons match the heads?

Where's my beer and that half inch wrench?

This might be a great build choice to use the comp dual conical valve springs........and a .904 lifter upgrade aswell.

The rotating assembly and heads were bought at the same time around June of 2012. The p51's had a few months wait. During the wait I bought a new Harley road glide and for the next 4 years I built , rebuilt and rode as often as possible. The heads were delivered to my dads house and I never saw them until a about 2 weeks ago when I decided to put this engine together.

That cam IMO is too much. Look at something like a comp XR292R is a great street cam & would suit your needs and driveline. 254/[email protected] , 671/678

All the parts are in except the 1050 dominator. It's coming from pro systems. Roger suggested a comp cam. 34-715-9. Today is build day!

That is a good cam for "Drag Race and limited use"

For street use? Keep a close eye on your lifters and lash. On the street the lifters will become a consumable.
You would do well to utilize a quality bushed lifter.

That's sucks to read. We told him street use. The lifters I'm using are the comp sportsmans. I dont remember if they were bearing or bushed.
