Sounds like they are in good hands..Bowl blending and SSR work is where the majority of power is at, your plans should work well.
I ported a set of swirl vane heads for a friend that wanted to beat up on my Nova with his Monty Carlo.
It was running ported and milled to 54cc 186 casting heads and 270H magnum flat tappet cam [email protected]
.050 and .470" lift on a 110 LSA.
I was running flat tops with 5cc reliefs or maybe 5.5cc and .028 piston to head clearance with the steel shim 3.2cc head gasket on it.
My compression was very high and cranking pressure was 245 PSI with an old fat stock starter.
I told him build a 383 and find heads and I will port them..He came over with a bunch of heads in the bed of his truck and the only ones that were not cracked were swirl vane heads.
I left the vane in it and ported them like I do all heads and told him the XE274H looked like a great cam to use.
That cam had not been out but a couple years.
I told him use 3.73 gears and one of his 700R4 transmissions with a 2400 stall and he should beat up on my Nova pretty well.
He put it all together and I ended up moving and we never raced but I heard his car ran excellent and friends told me they thought it would beat my Nova.
That is good that was the plan. I ran 12.55 at the time with 275-60-15 Uniroyal tiger paw tires and 3.70 gears in a 9" rear end in the 1978 Nova. Traction limited. Edelbrock RPM intake was used on both cars and 750 cfm carbs.
I later went solid flat tappet 235-245 @ .050 and a tunnel-ram and 295-65-15 Hoosier dirt track tires Chain link pattern.
Those soft spongy feeling tires that you can fold up and put in your suitcase.
Those things will flat hook to the pavement. Good enough for mid 11's.
You will always want to go quicker and faster.
Your car should be a fun ride when you get it finished. Keep us posted on how it turns out.
