yes thats the one. See im not good enough on the computer to get that and put it over here. There is also another cam in the same post which is alittle bigger. I know that this one is working well but I think the other one might of netted me alittle more horsepower. I do need this motor to last with all the college loans coming in from the kids I cant afford to do another. So I dont mind that the shifting is done relatively low (6200). I dont just unnecessarily beat the crap out of it. I did have the H beams put in so 6200 shouldnt be a problem at all.

I think your engine should last near forever at 6200 rpm.  I run 7000 rpm with factory rods.  Will it blow?  It might someday.

One reason I am so interested in your build is that I am getting ready to have a 470-474 inch FE built.  I want to run 10's with mild gearing and stall like you have, so it is a fairly close match.  My car is a stripped '67 Cougar which I think may actually be lighter than your Mustang. 

Another question if you don't mind.  Who built your converter?  And do you think it stalls as rated, at ~3000 rpm?  And how is it at cruising speed on the highway?  Does it feel like it slips a lot or no?

thanks,

paulie

Its nothing special its a TCI 3000 stall. Its not made for my car, and I dont think it slips alot on the highway. I never really paid alot of attention to if it gets the full 3000. I checked a few times when I first got it and if I remember correctly it was about 27-2800 its really hard to tell. With the short tires the 4.11s were to much. The car went faster when I put the 3.70s in.

I have 4.11 gears with 27" tall tires and a 3600 rpm stall converter.  Honestly, it is pretty horrendous on the highway.  Going 65 mph at 3500-3600 rpm with minivans blowing past you sucks butt.

Yeah I could never hear that motor screaming like that. 2700-2800 it gives me the willies as is. But I get it when I go places with the rest of the crew they hate waiting and driving so slow. But I will get there when I get there I leave earlier to give myself the extra time. I hate being late.
