Have an annoying rear main seal leak so the engine is out and getting a reseal. Only changes from the dyno are Holley 750HP and a Vic Jr intake.
Me and the neighbor had it out the other day and took it for a romp. The road has a pretty new chip and seal so traction was good which helps with the old tires. Made a 3rd gear run and the acceleration was awesome. With the car only weighing 2400# and the pull rod rear suspension the weight transfer is very good. You know the 1G feeling you get and all your innards move to the back, I've had a few cars approach that for a short time, usually at the top of the power band, or when making a turn on a road course. With both of us in the car, from the time I started the acceleration to when I decided things were unsafe that 1G feeling was continuous, I didn't mash the throttle but kept feeding it fuel and it just kept going. I was really surprised. The neighbor is an older gentleman who used to race dirt track motorcycles and probably other odds and ends, he let out a hillbilly holler like he'd won a pot of gold.
That was pretty good acceleration from the bottom of the power band up, didn't hit the rev limiter at 6500 or wherever it is at.
It also has that low rpm rumpity rump, have to be delicate on the throttle in turns, especially with the old tires. Going out making a turn the car hit the rump on the upswing and the car made a nice little 90 degree pirouette, neighbor thought that was pretty cool but totally unintentional on my part.
Lot of motor if it stays together.
