1962 Corvette Resto Mod build

Does the ECM also control the trans or is there another box for that?
are there other boxes for other things that might be causing interference?

Yes this is a brand new system that controls the engine and trans both. Pretty sure this also has the GDI box which controls the variable valve timing. I'm in thrash mode on that used motor and going to put that in the car.

Run Forrest run. I will at least switch out and put my Holley oil pan on it. Holds more oil and has better baffles than the stock pan. If I had more time I would continue to try figure out what the issue is with the other motor. At this point I have to get this car running down the road.

Well after screwing around all morning at least I got something done today. I would say she needs an oil pan anyway. Lol. Even this motor stock with a set of headers will make high 300s and 400 torque. No slouch for that light little car. Have to decide if we're going to run the variable valve timing or put the cam lock out in the phazer gear. Would like to just clean this up and throw a pan on it and install it..

Although leaving the dod in it and those factory lifters it will really limit the RPM on this thing. Probably around 5600-5800 RPM Red line. That will be interesting.

Well this car got started 5 years ago roughly and it has been an absolute fight to the death to try get a drivable car put together. Spent the last four or five days swapping motors. All I did was change the oil pan. Put the motor in and this is what the balancer look like running on the front of the crankshaft. You could see in the previous photo there was a big hole in the oil pan so that motor got dropped pretty hard on the front. Although on the front of the balancer there is no damage showing where it hit.

Base tune is done and has not gone on the dyno yet. Motor sounds real good other than I feel a slight mechanical vibration. Jury is out whether it bent the crankshaft or not. It's not uncommon for these motors to vibrate in the later model trucks. They have those big crazy motor mounts and this thing has very stiff mounts to a Morrison chassis so you're going to feel everything. So we will run it on the dyno and beat the s*** out of it and see what happens. So this 100% tells us that something happened to the cam or lifters in the other motor. Beyond baffling. I will save that motor on an engine stand and stuff it in the corner for now. I have a feeling this thing's going to rip even with this stock motor. Should be 400 horsepower and over 400 foot pounds of torque. I called Morrison today and he said the chassis weighs very close to a stock C1 chassis. Although there was a lot more weight in the rear due to the heavier 9 in axle and then the tubular a arms in the front are a lot lighter. Rear end gears were making some noise in this car so I will be putting a set of gears in it. Drive it first and see what I want to do. I think we will set the rev limiter at 5800 which is stock. I could not wait to wash two years of grime off of this car.

So weight on the car should be around 3,100 lb. Pretty light. Stock GM vibration mount versus the dense urethane mounts.

So a funny story. When I put the supercharger on my 02 ZO6 I did a dual disc McLeod clutch to handle all the extra power. Called them up and said do I need to balance it they said no. Well I put the damn thing together and it had a slight vibration at about 2500 to 3,000 RPM. Of course on that car you have to pull the entire cradle and the torque tube to get to the clutch. Basically gut the car from the engine back. Pain in the ass. So I thought what if I start playing with washers under each of the six clutch bolts. So I started going up and down with the car putting little thin washers under the bolts and I'll be darn if I did not get that thing as smooth as a baby's butt. I think it took me about 22 tries and half a day playing with it. It's still running that way today years later. With that said if this crank was tweaked slightly on the front but would still run I would not be afraid to start playing with little weights inside that balancer and then JB weld it in place. Of course that's a MacGyver way and just a temporary fix but right now with everything else I have going on I just needed to get this car going down the road and driveable.

At the rear wheels 341 horsepower and 367 ft lb of torque. Our mustang Dyno is very stingy on numbers. We have run a lot of cars on this Dyno over the years and I can tell you that is a lot of power and torque for a 3000 lb car. Should be an absolute blast. Going to drive her home tonight I think.

 

[Bobalos]

Nice job. super cool hot rod.

 

[onanysunday]

Well after 5 years got to take it for its first real drive home tonight. 22 miles from the shop to my house. Awesome is an understatement. So effortless with that much torque and a light car. With the old style halibrand 15" wheels and only a 235 BFG wide rear tire at 55 mph and shifting from second to third it barked the tires pretty good. I think my dad would have loved this stock motor in the way it works better than what we had put together in the other motor with the big cam. I believe the cam in this is under .500 lift and the cam in the other motor was over .600 lift. This runs so good I'm probably just going to leave it alone and drive it. Just sell that other motor versus keeping it.
