Top end suggestions

Your car was moving fast because of it's light weight.
You would only need about a 300 horse engine to go mid to low 12's and that's what your car was doing with the 318.

Two big improvements would be a way bigger carb.
Try to sell the smaller holley 650 and put the rest of your money in a good hp 950 cfm holley or 1050 crm dominator hp carb.
Secondly i would go with a victor single plain intake.

As far as the cam goes, you would need to know what the head flow #'s are.
BUT...............................
This is one of those situations that everything might be matched up perfect with your engine but the car is going to need a ton of attention.

You might have hooked up before with the stock converter and a cam that was way to big because the car DID NOT MAKE MUCH TORQUE, and moved nice and smooth out of the hole on the starting line because of it.

Your installing a stoker in a very small car and will have a ton of torque.

I hope you have wheelie bars, cause i think you might need them.
Maybe you won't, but i would definitely talk to as many people as possible that run anglia's at a drag strip to understand how they react with certain engines and power levels.

You might have wheelie bars all ready and have a good understanding of the vehicle and it's problems ----- and if that's the case then forget what i just said.

Good luck with the heads and pick your cam last based on the end result of the heads and the work being done.

That 3500 converter might stall at a lower rpm due to the light weight car.
What kind of converter is it???????

The car didn't hook before - it covered the 60 foot like it was going uphill. No torque at all.

So yeah, I realise the chassis tune will keep me entertained but its running a 4-linked 9 inch with plenty of adjustment. Too much air under the front tyres would be a nice problem to have, as I plan on running treads at the track (Sportsman Pros).

Head flow is a little bit of an unknown but I think around 280 at .550 or .600 would be a start. Having said that, I fully expect the 3.94" bore to have an impact on the bench figures, and obviously the intake manifold will too.

If swapping out the carb (as opposed to stepping up to the Proform 750 centre) is needed then that's what I'll do. I may go to a specialist like BIGS or AED once I have the rest nailed down.

Not sure what the converter is - it came as an unfitted spare when I bought the car, and I subsequently had a trans specialist check it over. The bets were on it being a Turbo Action item. If it doesn't suit the car then that will get an upgrade too. I had thought that the high torque output and low weight might cancel each other out to an extent.
