Today, dollar for dollar, is the 318 faster than the 340 ???

I will never build a NHRA Class race car so a 700 HP 528 is not going to happen. Rich boy racer above can have at it.

My desires are to build a cheap go fast car/truck. Will it make 300 HP? I don't care.
For my Little Red truck I almost bought a Lunati 'Thumper' cam just for the lope but its the wife's truck and she would not be happy.
My son has a 5.2 long block that I may build just for the Loppy idle and put it in my 1984 Rampage.
Lunati rollor cams run $259. Rock Auto has stock 5.2 hyd roller lifters for less than $6 each X 16. Need some 6.950" hollow pushrods, Trick Flow are about $100.
Never heard of a 700 hp 528 NHRA Class car, or is that a generalization statement?
