There should be a little resistance the first time you turn it over but after one or two turns it should turn over easily by hand.

If this does not happen then it's time to dig deeper, intake off, heads of etc.

In the early 90s my dd 66 ate a rod bearing one friday and i wanted to hit a huge cruise sat the day after,

I had a 327 that had sat from around 1969
It was in a mid engine kit car,
I did the power drill primer thing, turned it over by hand and rigged up a fuel can batrery etc, it ran,

So i get busy and in a few hours had the 350 out of the 66 and 327 in,
Everything seemed to perfect, way stronger than the 350,
But....
All the seals in the 327 were dried out, the rear main seal really had a bad leak

Wish i had thought to change them before installing it

I found a 400 SB in a wagon that had been sitting outside 10+ years. Shoved into the back yard on the grass and parked without doing anything to store it except shutting it off and walking away. It sat there through rain and snow and whatever else mother nature dished out. I replaced the battery, hooked a plastic tank to the fuel pump to give it fresh fuel, poured a little gas down the carb and fired it off. Then, pumped up the tires and gave it a pull to get it out of the holes. Drove it home to tear the engine out. It ran great in the Beaumont I installed it in over the weekend to keep the car running. No leaks, no oil burning, no carb issues, etc.

So, your engine should be fine being stored inside. You have nothing to lose by playing it safe and both putting a little oil in each cylinder, changing the oil and priming the oil system. So, might as well do those things. Otherwise, fire it off and enjoy it.

If it is a flat tappet motor then proper zinc Rich oil is a must. With that said, I would remove both valve covers and the distributor and with a good quality priming tool I would spin the oil pump for a couple of minutes and then by hand give the engine a quarter turn on the crank. Do this for two whole revolutions while making sure oil is coming out of your rocker arms. Once done stab in the distributor install spark plugs and make sure cooling system filled and leak free then let er rip. Once she fires, quickly bring it up to between 2000 and 2300 rpm and hold for a half hour while kicking the throttle a few time during this period. After 30 min shut down, remove valve covers, disconnect 12v to distributor and using the starter. Have someone crank the engine over while you observe the push rods to make sure all of them are rotating. If they all are then you are good. Put it all back together , change the oil again with the same type of brake in oil and hit the road. If a
not all the rods are spinning then your cam has not been broken in properly. My 02.

Is that one OK?

Also, what problems are there with the CF and the 350/290? This is the first I've heard of that, but then again the CF will be new territory for me. I've got Q-jets and TPI down cold.

Thanks,

What year vette is this motor going in? Since you have CFI system, you will need the ECM as well. The 82 ECM really was never hacked unlike the 84 ECM. With the 290hp 8:1CR motor and CFI, you will have vacuum issues and it will not run correctly. The base CFI motor was 9:1CR.

I think if you install a stock crate 195hp motor which is 5hp less than the stock 82 motor new, you are already shooting yourself in the foot IMO. So, how does Jegs or Sumitt suggest you get 260hp while you are running CFI? If I were you, instead of going with the CFI system which I run without issues on my 82, but heavily modded, I would run EFI or throw a carb on it and call it a day. I think you will be farther ahead in the long run and much happier.

This is all based on the fact that the motor is still good and will run after you test some suggestions out. Good luck with your build/mod.

That's right by golly, I never did mention the year...it's an 84. But being I'm a C3 guy, I asked the question here. The engine has already been installed and the CF parts put back on...it has sat like that for the last 13 years. I'm contemplating buying the car IF the engine put in would not create issues...the last thing I need to buy is trouble. I have enough of that now and I haven't had to pay anything for it!

Jegs and Summit advertise that for propaganda purposes...IF you add this, that and the other you can "potentially" generate.... Well, you get the idea. They say nothing about using it with a CF induction system.

Make that nine.

That's because the car sat untouched in my garage for most of the 15 years.

Oh! It that case it had 205hp back new. IMO, I think you are starting out on the wrong foot with that motor and CFI. Something to think about though.
