I do have the wiring correct for a 351W. And the engine does run good, i am proberly just had my hopes up to much, and exspecting a big block perfromance out of little 302. I do agree with your statement about the gear ratio. I have 350 grears in it, I though I had 4.11's and I did mess up am put 38" tires on it which killed me even more. I have listed all of the copmpnets of my moter below. Tell what you think and what I could do to get more power. when i was builing the moter, I was trying to find a happy medium between low end tourqu and a high reving moter such a dragster you could say. I really built this moter around a 125 hp Noz kit i have and that I did plan on installing. But I never did get try it yet and just might not worry about it.

I do have a question though. I have noticed that my engine loves a lot of timing I think i have the initial timming set at 22 - 25 right now and I couls still go more unitl it bites the starter. you know what i mean. so how do you where to set the timing at?? I think with noz you cant go above 32 degs toal timing right. I tryed several things like locking out the Dist,, changing springs ect. but nothing make a real diffance.

Oh and I have the world product Jr's and I did not port or gasket match. Soi know that one week area I have. I read that once you port these heads it really wakes them up. what i really want is some alum. heads I hear trick flow is right up there with best perfomance.

oh yea one more thing when I put that big cam in I had to use a adjustable push rod to get a measurment for my new push rods, so when i order the push rod I gave them the leanght that I measured, they did not send me the excact leanth I ordered but it was real close. but i did not degree the cam. so that sould make a differance as well right?

I really want to thank you for your help, I have learned so much sence this project began I will send you a pic if can figure out how lol I think you will love it..
