454 seems to high
I got some factory bbc stands but my engine seems to be too high in the front.i haven't fixed my crossmember for the th400 but I cant jack it up any higher in the back due to the transmission hitting the body.does the motor need to be level?

Re: 454 seems to high
Doesn't seem to be that high. If i recall, they don't sit level. Here is a picture of my 402/700R4, obviously the 700R4 is not the same length, but close. I'm sure it's fine.

Re: 454 seems to high
Mines not level either. Has a slight tilt to the firewall.

Re: 454 seems to high
Make the carb mount level. Adjust it at the tranny mount. They normally tilt back. About 3 degrees downward.

Re: 454 seems to high
Mine ended up at around 4 1/2 degrees. I will adjust the pinion to make it work

Re: 454 seems to high
The only way I can get the carb plate level is to change the front stands.I can jack the rear of the transmission up till it hits the truck body an it's still not level.the way it's sitting now I have just enough clearance between the transmission an the body.

Re: 454 seems to high
How tired are your body mounts ?
I put a 454 and TH400 in my shortbed a few years ago (low hump cab) using those same factory mounts you're using. The trans hit the body until I swapped the old saggy cab mount biscuits for new ones. Then it cleared plenty. It goes without saying that you have the wrong trans crossmember and mount in there currently. I assume that's what you're leading to when you say you havent been able to do that part yet.

Re: 454 seems to high
I didn't take a ton of pictures back then like I do now (pre camera phone days)
