Does any one know if a GM HEI distributor with the big cap will fit in a 1968 Camaro with a small block 350.Is their any clearance problems with the firewall?
Thanks

I had no problems at all, but some have had to "mod" their firewall. Its a 50/50 shot.

It all depends on whether or not the frame has moved and some of the following???????????? If your frame is in the correct position on the body and you have original motor mount perches and transmission crossmember, an HEI will/should fit. To see if the frame is close to where it should be, use a slightly less than 5/8" (.610") rod about 1 foot long and slide it into the holes next to the forward body mount and through to the corresponding hole in the body. These are the alignment holes the factory used (among others) to align the body on the subframe. The pin should be at 90 degrees to the frame and rocker panel. There have been many posts asking this question and some of the answers have been as drastic as taking a hammer to the firewall to make it fit. The position of the frame and engine and even the intake manifold (yes you can move it a bit) are all factors to consider if you REALLY WANT A LARGE DIA. HEI. I would be checking to see if you have original motor mount perches, motor mounts and crossmember (wrong crossmember sits too low and causes the engine to tilt back). As a last resort if you only need an 1/8th or so, I would pull the intake and reinstall it with the HEI in place and bolt it down with the clearance you need. Obviously you don't want to misalign the intake runners, but you can gain a little this way with most intakes. The only other solution is get another style of distributor

320/350 small block mounts put the engine farther back than the 307/327 mounts- and the people that have issues with clearance seem to all have the 350/302 mounting setup.
i've had 2 Nova's- the first one was a 70 that was a factory 350 car that needed some "work" on the firewall with the trusty FOrd tool to get the HEI in, and one was a 71 that had the factory 307 in it that had about 3/4" of clearance with an HEI installed.
a good way to find out what mounts you have- but no a foolproof way- is to look how your headers fit around the power steering box(if you have headers). most (but not all) headers were designed for a car with a 350- so if you have a good sized dent pounded in the tube to clear the box, you probably have 307 mounts. but Dynomax headers clear just fine in a 307 car, however, so it isn't a foolproof method.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

I remember from earlier posts that they reached the same conclusion as novaderrik posted.

FWIW, HEI on my original 327 68 fits with no problems.

What mounts position the motor most to the front of the car and which ones to the rear?
