Maintenance / Re: No carbon in exhaust port of 396.

« on: March 18, 2010, 09:22:08 PM »

Water level in radiator is pretty constant and doesn't overheat. Motor is supposed to have been rebuilt so I would not have thought this would be a problem in case I got a dud.

Thanks  tmodel66. Theres carbon in the header tubes except no. 8, thats how I noticed this problem. Cam is hydraulic. Swapped plugs around and they are all new but its still the same. It has new leads and rebuilt dizzy so I don't think it's electrical. Next thing will be to check lifter and compression.

Maintenance / No carbon in exhaust port of 396.

« on: March 17, 2010, 09:36:54 PM »

Bought a rebuilt 396 just recently but cant get it to run properly. There is no carbon in no. 8 cyl exhaust port whatsoever, clean as a whistle.Took rocker cover off to see if valves were opening and closing on that cylinder which they were so it has me stumped. I thought if the cyl wasnt firing you would still expect to see some residue or petrol in the port. Any ideas.

General Discussion / 68 Camaro Heater box

« on: February 21, 2010, 03:24:33 AM »

Was wondering if the inside dimensions of the heater box where the core sits is different between BB and SB. Went to fit a 68 BB core in my box and it seems to sit too high and I can't fit the clips on. My car runs a BB but was originally a SB.

General Discussion / 68 69 Subframes

Does anybody know for sure if 68 and 69 Camaro subframes are the same. If they are different can anybody tell me in what way.

Measured the height of my frame mounts and they are very close to the measurements that Marty posted. Looks like now that the problem may be with the gearbox crossmember and mount so I shall have to do some more homework.

Thanks for that Marty. I can compare my frame mounts with your measurements and take it from there.

As I was saying in my earlier posts if I could get the correct measurement from base of frame mount to the centre of the bolt holes on both the RH and LH side this would stop all the guess work. Maybe my repo frame mounts are the result of a bad batch run and aren't right. If any members have an original 396 engined camaro and could take some measurements for me that would be greatly appreciated. As I also said the engine mounts are genuine GM and correct for a 68 camaro with 396 so the problem has to be with the frame mounts or tranny crossmember.

Marty, the car was originally a small block. The tranny is a turbo 350 with the original crossmember. It's always been in the back of my mind that this could be the problem as you stated, that the tranny is too high and is therefore lifting the front of the motor down to much. Does anybody know if this the cause of the problem for sure and if so how do I solve it? Has anyone done this engine swap with a turbo 350 and found the same problem?

William, yeah the brackets are different heights. As I said in the first post I bought these at classic industries and according to their books these are the correct ones for a 68 with BB. Maybe I'm wrong but it just seems to be too low to me, the carby does not sit level, it's low at the front.

William, the motor mounts I'm using are genuine GM 6258154 and the instructions inside say that they are correct for a 68 Camaro with 396. There are no gaps when fitted to frame mounts. I've tried to fit 69 motor mounts to my frame mounts but the 69 motor mounts are too narrow and wont fit over the frame mounts. Does anybody have the base to centre of hole dimensions of their frame mounts LH and RH side in a 68 Camaro with 396 in which the motor sits correctly.

These are the correct part numbers for the frame mounts and motor mounts for a 68 camaro with BB as per the following site. That's why I can't work out why motor sits so low in subframe. http://www.pozziracing.com/camaro_engine.htm

I've put a 396 engine into a 68 Camaro using repo engine frame mounts purchased from classic industries. They are stamped with numbers 3912597L and 3912598R which are supposed to be correct. I'm using new original motor mounts 6258154 so I assumed everything was right. The problem is the motor sits way to low, the fan hits the bottom of the shroud and the front section of the sump nearly rests on the subframe. Has anybody got any ideas as it's driving me crazy. Something is wrong somewhere and I can't figure out why.
