blittle chances are he is closer to his hp mark around the 7k mark rather than 6k mark....i own a few of these bbc...my 632 made max hp at 7600...my 511 seems to peak at the 7000/7200 range....

6k is not even close to turning one of these big blocks power range.

thanks for the input tho..keep it coming

I understand these motors should be capable of running a higher RPM than 6500 range. But looking at the setup and considering it's 10:1 motor I thought that might be a bit high.

When I take into consideration that I'm running a SB 409 CI. to his 502 in a 3500 lb camaro basically the same as his with a 4.30 gear with 29x10 slicks with 8" Hughes converter and ruinning 60' ft. in the 1.35 to 1.39 range on the t-brake and 1.45 ft brake leaving at 3000 all day long and never turning more than 7000. Well, something just doesn't add up in my feeble little mind, sorry. :lol:

Also his car is lighter than mine and has 92 more cubic inches. But 4 points less compression. I know a low compression motor doesn't really make good power at a high RPM.

I think we all agree there are many variables that can affect the performance. Tune up and chassis setup come to mind. Looks like he has cal-tracs and leaf springs on the car. This could also give him problems. Nothing wrong with Cal-tracs but there is an art to making them work well.

Actually it is a 540.

Ok, well that makes this situation even worse, right! :wink:

Man with a 540 that thing ought to be spankin my butt. I suspect there is more to this issue than just a converter. Although the TCI wouldn't be my choice at all.
