Ran a 1968 Nova in D/MP in the mid-70’s; 331” small block, tunnel ram, big ol’ Dana 60 with 5.14’s. Would go 10.04 / 132 mph against a 10.15 / 135 mph class record. Then Reher / Morrison showed up with their 287”, 10,000 rpm ‘65 Corvette and went 9.44 / 139++ mph, only to get quicker/faster every month for a year. I was hopelessly outclassed. So began a continuing theme. :p
But. A Chevy Of any size, in a Cobra, is heresy. Blasphemous! Best to sell the Cobra and build a Cheetah......

Re: Motor Parts
Here are a couple of pictures of my progress on the motor.
I have all the rotating parts all balanced, and I'm starting the pre-fitting of the rods and pistons. So far it looks like I only have to do one small relief spot on the bottom of each cylinder.
The only problem with that is that I want to be careful and not take too much. The book states that I only need around .035 clearance.
But to be careful I seem to be taking the crank in and out 2X's for each hole. Damn thing weights around 60lbs. Hope to get better at guessing the amount as I move thru the motor.

Re: Motor Parts
Ken,
Looks like you're making good progress, how long do you figure before the motor goes back in the car?

Re: Motor Parts
Not sure...it really is almost done except for the assembly. I just have to keep motivated. I figure that I can make good time on it while the fiberglass resin is drying on Tom's car.
Tom asked me to try to attach multi photos..so these are reruns.

Re: Motor Parts
You'll have your work cut out for you repairing Tom's car...that damage will be a challenge to repair properly, but I have faith in your skills...
Re: Motor Parts
Not much visual to show. All of the cylinders have their notches for the rods to clear. I'm almost finished form fitting the crank scraper.
I did have a little disappointment thou. While the 400 2 bolt block has wider and stronger main webbing than the 4 bolt I had planned to use studs instead of bolts. But more research has informed me that it would need to be line honed do to different stress loads. I hadn't thought of that. Good thing Summit Racing has a good return policy.
Soon it will be time for hot soapy water and a blow gun. Fitting ring gaps should be all the fiddling work left to do.

Re: Motor Parts
Managed to get all the holes filled. Fitting the rings was a bigger job than expected. The ring filler made it much easier. I also bought a tapered ring compressor while it only fits the 4.155 bore makes me wonder why I waited so long to get one.
