P5b Exhaust Manifolds

[pmd400]

Firstly, I've put this on the p5 section rather than the p5b section. Can the forum admin please move this thread?

Does the centre dump exhaust from a p6b actually interfer with the steering box and/or idler arm, or is this just an assumption? I've currently got a small block chev sitting in the car with engine mounts but very close to the correct position and angle and centre dump rams horn exhaust manifolds fit really well

Your query was answered initially but you're still asking the same questions! Don't compare apples to oranges, a chevy engine is not a Rover engine. This type of engineering has all been done before by member's who post to this forum, specifically in the Modified Section. Other related technical problems with pursuing this type of conversion are also covered.

If you're an Aussie, Scott (and Mark Richmond) of "Scott's Old Auto Rubber" did a legal Chev V8 conversion years ago. See link below.

If you read the above link note that Scott states having the engine slightly raised at the front was not an ideal situation in his view (unfortunately incorrect.) He states that this causes issue with the transmission/driveshaft alignment (incorrect again). Driveshaft alignment is a matter of pinion/flange angles. These are easy to correct if you know what you are doing.

Scott had overheating issues with the conversion as will any other builder who decides to mount the engine level. Steam pockets form at the back of the block in the cylinder head as entrained air will not purge forward to the radiator or purge tank. The front of the engine should be higher than the rear unless you want constant overheating issues due to trapped steam pockets. The mistaken fix is a larger capacity radiator. Overheating and coolant purging (due to internal steam pressure) then becomes a permanent problem.
