I recently got a knocking coming from my engine. I'm 90% sure its a rod, due to the fact that I lose all gauge oil pressure at idle. I've decided to replace it with a remanufactured short block due to the short time i have allotted to work on it. The company offers 2 cams that should work well with my head conversion (GT40 heads) the FMS B303 and E303. I'd like to get a good power range with my 5 speed transmission and 3.55 gears, but I'd also like to keep some good streetability. recomendations?

I recommend you shop around a bit more for a builder that's moved on from letter cams.

I dont think you will gain a lot of power from a E303 cam just idle noise, but I may be wrong. I have used TFS stage 1 cams with my mild set ups. good sounding and mild power increase, also works with stock springs and lifters.

i did, and like i said on the above, i have a limited time as i'm in the navy and can only tinker on my days i'm not working, which are few and far between, he was also the cheaper option with having the shortblock assembled and shipped

Ya it is a nice cam and was streetable in a mild build, also has a nice idle noise. Im not sure what your plan is for your stang, but just getting a low mile short block then buy some used aluminum heads and do a H/C/I would be a nice upgrade and still in the budget compaired to having someone build you a short block. can usually find a good 302 for around $300 maybe cheaper if you look in the right places. But to each his own.

Well the motor got pulled today, so there's the first step. I ended up going with the E cam. The guy I talked to said he gets pretty good power out of his with a bit of a timing advance. I'm going to go ahead and put my GT40 heads on the new block as I'm more a fan of iron heads on something im going to be driving so often. Thangs for the advice, it's much appreciated. I will post more when I am closer to getting the motor put back in.

That set up should work nice with the 3:55 gears.

Almost There!

Finally got the key turned and the new block fired up last night. She runs great! Couple more bugs to fix and it'll be finished
