What a clown you are, cupcake. I posted a thread from the race section with more than a few 318's with times in the 10's and 12's. If you actually built motors, you would know that 318's use the same rod forgings as 340's. The cast crank is fine for well over 300 hp, 340's used them in 72 and 73. Why keep small port heads, when used 360 heads are cheap. Stock 340 intakes are cheap, stock TQ's or AVS's are cheap. All you need are a set of pistons, and a cam kit, and some machine work to beat a stock 340. Easily done in under $3,000. Am I going to build one to stick it to some clown on the internet? No, I have 340's, a 5.2, 273's, 383, a 440 and early Hemis. But I do know how to make anything run.
