I'm putting a Buick 225 into a Triumph GT6+. If that engine dies I have a Buick 231 to replace it with. I have an ex-Camaro T5 sitting in place now but it's a bit large as I cannot take TOO much out of the narrow frame rails. I also have a Merkur T9 box which would be much easier to fit into the available space. The Merkur was a 2.3 turbo car, HP was similar to the Buick V6 but I doubt it had the same torque. T9 boxes are rare in the U.S. so no one here appears to know much of anything about them. How strong are the T9's from a practical point? My Buick V6 could be considered interchangeable with a Rover 3.5 or 3.8 for HP and torque. Do T9 boxes survive behind Rover engines in light cars? Not intending any drag racing, more a fast road/track day car.

Anyone here sharp on Ford Kent 1600 engines? Just bought a core 711M push rod 1600 to build up for my Marcos 1600 GT. In the U.S.A. these are usually found in Formula Ford's with strict limits on what may be done to them. My Marcos is a road car and I have no limits on the build beyond that. So piston size, valves, cam, intake (I already have a twin Weber intake) are all "Free" to be as I like. Looking to make around 125 HP at 5000' elevation. No one local to me has a clue as to how to proceed.

Seems this is the place to be for hot-rod british cars. Also on some other forums but few get into details of older Brit cars and how to improve them without essentially dropping the body on a new chassis. I'm modifying a Triumph GT-6+ with a Buick V6 engine, T5, and custom IRS. Currently looking at Merkur rear suspension components and custom "A" arms. Big project, should be fun. Also restoring a Marcos 1600 GT wood chassis car. Returning it to near original, last engine was a Mazzzzda rotary, and a horrid fit. Finally located a 711M 1600 cross-flow for it. My only major mod is fitting an ex-Merkur T9 trans. Have a few others, '68 El Camino hot rod getting Jag IRS, four speed, HOT engine. 1969 Land-Rover 88" with quaif diff's at both ends, Fairey OD, roll bar, etc. Have taken it all over and back. Been playing with British cars since I was 12, first car I ever bought was a Jag XK-140 MC drop-head. Lost it to flood damage before the restoration was complete, many years ago. Have had about every sort of Triumph, several Jags, Alfa, Morris, MG, Thames, really too many to list. Have done several kit cars, from old 50's "You build it" body shells to Noble P4's. Currently have the molds to the Tatum Crusader, plan to build one with a big bike engine. Have a fairly well equipped machine shop, may make more than one of certain items I need. Main project of the moment is the TR GT-6+. TRIumph + buICK = "Trick-6". Major issues are front and rear suspension redesign.
