Do you have a Twin SU manifold?

Twin 40mm DCOE's are a dead end, unless you have some old ones already. 45's are pointless until after you have spent a couple of thousand dollars on the cylinder head, that is like fitting a 1150 Holley Dominator to a 305 SBC.

Don't buy the cam from IPD, go to Isky who are the actual manufacturers or somewhere else like Schneiders. Where are you located?

If you buy a 123, MAKE SURE IT's THE PROGRAMMABLE MODEL

Do you have a picture of the head? Can you get yourself 1 or 2 more old long motors?

What is your car? What is the purpose of the car? How much $$$$$ have you got?

If you are only going to +.030" on the bore, then you are going to be missing out on alot of power. +.125"/92mm is what you want for a performance engine because it unshrouds the intake valve, I offset bore towards the intakes.

Tinustuning.nl is one good source for all your parts if shipping from Europe is no problem for you.
