The body work and clean look are fantastic. What I also appreciate is that you strengthened up the frame as well.

I had a Triumph TR6 that I swapped a 351 Cleveland in without modifying the sheet metal frame. It was a beautiful car, appeared to handle decent enough and accelerated like a rocket. Give it a bit too much throttle in a turn and/or if the turn had an uneven surface, the car rewarded you with a quick 360 view of your surroundings. I didn't realize it at the time but that TR6 frame had enough give to cause this phenomenon. After the first couple of spins, I learned to keep a light pedal on the street. On the autocross course, the car was sideways more than straight.

My fix was to sell it and build a Cobra (which is still my daily driver 20+ years later). My only regret in making this change is that I lost the "sleeper" British car look. Nobody's surprised when a Cobra blows then away but they are shocked when a TR6 does it. I bet your's is fun that way
I didn't want the car to flex (and it doesn't) but the result is that it is a little heavier than I had hoped. Any reduction in weight would probably be accompanied with a reduction in traction. I haven't raced anyone on the street yet although there have been a lot of cars trying to get me to. I guess I'm just getting conservative in my old age.

Kerry - this is an update on the brakes. Without power assist the brakes stopped well around town but a full on panic stop required a lot of pedal pressure. I found some 7" diameter remote mounted brake boosters (VH44) that were OEM on some Australian cars that were small enough to mount in the car. I didn't want to clutter up the engine compartment so I mounted them in front of the front tires under the headlights in the fender well. I needed one for each brake circuit (dual master cylinders) the front booster is on the right and the rear is on the left side. I made a vacuum manifold out of 1 1/2" tubing that plumbs vacuum to both boosters and provides some reserve vacuum for multiple stops. The brakes are now phenomenal and require much less pedal pressure to lock the wheels. With the sticky wide tires you generate a lot of stopping G's before the wheels lock.

Looks great………. like that’s how the factory should have built it. You certainly should be proud. ~ John Buchtenkirch
