"The problem I have living where I am is that I am surrounded by hills and that MG motors never really had sufficient torque to deal with steep and long grades. The V6 promises 200 ft/lbs of torque. The hp is somewhat irrelevant. It weighs a few pounds less than a MG motor, but should retain all of the original weight characteristics in terms of suspension and handling, tires, etc. I reckoned the 1622 got in the range of 18-20 mpg. I would expect better with the larger motor. It is a 60 degree configuration and drops beautifully onto the MGA motor mounts. The only remaining problem I foresee within the engine box is headers (this cheap bastard may have to actually buy a pair from Bill Guzman or Brian McCullough).

Within the engine box, I got 2 simple round biscuit motor mounts with single studs and then bolted them down to existing holes in the MGA frame perches. I used 1/2-inch steel plates to secure to existing holes in the Camaro block and brought things forward to catch the old MG mount points. In the case of the driver's side, there was interference with the lower radiator hose and I had to cut out a small crescent in the original MGA perch for its passage.

To accommodate the T-5 transmission mounts, I welded a steel plate across the two center rails of the floorboard structure, welded up a mount bracket, and used my old favorite simple biscuit-type rubber mount.

Plate for tranny Plate, mount/biscuit, and T-5

The third modification from stock involved putting a dimple in the tubular frame cross member strut to accommodate the external slave cylinder for the tranny. As we know from your tutorial with the torch and substantial compressed air to 'pop' them out, those pipes get pretty bashed in and I was not too concerned with originality being compromised on this aspect. So, then, 3 totally easily restorable modifications, if someone should actually wish to put things back to 'stock'.

Welded mount A Trivia Question - Renold Key Fob

Relevance of the RENOLD key fob? A little trivia. After my father demobilized as a Chief engineer in the Merchant Marine in 1946, he came to New York seeking a job with all those other recently laid off servicemen. He got a job as a mechanical power transmission engineer. One of the product line that he carried was Renold Chain. He was US sales rep for Renold. Hans Renold was a Swiss engineer who came to Manchester, England, invented roller (or bush) chain, and founded a company in Manchester to manufacture it. Renold made all of the timing chains for all the British car companies for many years".
