crazy_canuck999 said:Well that's what I was thinking, and I thought stock 5.0's rwhp was about 185 stock.

How do you like the thumper Heads?90mustangGT said:From the diagram, it looks that the p/c is a boxed X pipe, but a little more open towards the inlet side. That probally explains the echo, hollow, liquid sound it makes.
Ummm, it's winter, ummm, track not open yet.
I was planning on a dyno run on my day off work on thursday but it snowed, the one day I have plans and it freakin' snows, in Georgia.Tax refund in, ordering tires tomorow. I'll have some money left over, I'm not sure what to buy with it.

How much??90mustangGT said:I like them alot, they are definatly an awsome upgrade, especailly with the valve spring upgrade, but I may be outgrowing them. Many people try to say they do not perform any better than stock, one idiot even said that he knows "this guy" which lost power with them, that is just plain BS, but I am thinking I am starting to outgrow them. I am thinking of a FTI combo but that is a lot of money, but I want a different cam and if I do I'm going custom and why do that alone and not get some heads. It was a good stepping stone though. I think if I do, I will keep these heads in case I get another SB Ford powered vehicle unless someone gives me a reasonable price for them.
