Chevy engine position

[Robbo]

After much mucky about, I'm about to mount my SB chevy engine into my Classic Replicas Viper chassis. The Viper chassis doesn't have any engine mounting points at all. So I'll have to weld some brackets or something. Does anyone know if the chevy needs to be "angled back" (i.e. the back of the engine is lower than the front) like the SB Fords? If so, by how many degrees?

Any help from someone who has done this would be appreciated.

Thanks

HI,
engines usually are angled back slightly, the thing I was told to make sure of is that the carb top/ air box is level. This ensures the correct tilt to the engine I beleive as the manifold/mounting plate allows for this.

In cars like these the main thing is to make sure that the output shaft on the box has a clear view of the flange on the diff, the sump or bottom of the bell housing isn't likely to hit the road and that you can close the bonnet. If you are worried about the angle of the carb, you can get tapered sandwich plates to mount it on.

If your chassis is rectangular as opposed to tubular, DJ Sportscars will sell you mounts that will weld to your chassis (but you need to compare distance between the rails. Originally I had Jag mountings and changed to Chevy. The easiest way I found to acieve this was to weld the mounts to a section of angle.I then put the mounts in place on the engine and lowered into position. Couple of tack welds and engine out and weld fully. It allowed me to move the engine approx 2" further back than on the standard giving slightly better weight distribution.
The engine can be mounted level and levelling of the carb can be carried out with an angled spacer which in itself can improve low down torque on a slightly tuned engine.

I find the angle of the prop shaft and the angle of u- joints much more critical than the engine tilt and carb angle.
Years back I got some vibrations from the driveline, when the pinion angle and u- joints was out of position. Should be slightly offset related to the gearbox ( It was a Dodge Challenger, NOT a Cobra )

The engine and transmission have now been mounted in the chassis. Reasonably level and with good clearance (I hope) for everything. I ended up fabricating my own mounting brackets, but its worked out well.

Thanks for all your advice.
