Hello
I need some good input from you all that know more than I do.
So I know a little about my combo but Not everything.
I owned the car years ago and now have it back with a complete new setup.
It’s a 69 RR full steel, dash mini tub small tire.
mega block 528 built by muscle motors.
Indy -1
Comp cam roller 682 intake 663 exhaust
Diamond pistons dished part 52424 4.350 bore 24cc
R&R Billet Alum rods

7al2 and grid
8261 Pro Power HVC-2 Coil
Crank trigger
Locked out at 36degrees
Fresh Gary Williams dom just back from his bench
NOS Proshot Fogger with a Edelbrock controller and a leash board.

Andy Mayes built the tranny
No info on convertor

Dyno at 798hp

Nobody can tell me what compression it is unfortunately the guy is not able to
Provide details past the paperwork they provided at last freshen.

The car went 9:03 @ 148 with 300 shot and 116 octane (got the video) just before I got it back.

I’m concerned about:
They ran NGK R5671-10 gapped at 20 the driver/Mech
Said he threw them in there because it’s what they had for their blown alky car.
People have said way cold…?

Fires up quick, idles great, no missing, popping or anything.
I’ve drove it last weekend on the street just to get a feel on 110 octane
Seemed “ok” but got a little warm 215 after a couple of
Romps and about a 7 or 8 mile round trip
so I don’t know if all is up to snuff with cooling.
Got a Meziere pump and a aluminum rad with a pusher and a puller.
It was 80 here in SWFL.

I want to get it on the dyno or do some short track pulls but where do I start with plugs and gap
For non spray. I don’t just want to go in blind to spraying it off the bat.
I’m not the best at this and new to the big boy stuff.
I used to race this car years ago as a 451 but had a good tuning buddy but now on my own.
So any foresight, suggestions or help I’d appreciate it.

Anything else I can share to help let me know
I’m an slightly informed newbie so all helpful comments welcome
Thanks I’m advance
