Default Updated on my Engine Build

Just a quick update.

Should be measuring for my pushrods today.
Engine is already primed with oil
Double check my accessory brackets and drill if needed.

Then I'm ready to install back in the car.

Starting to look more like an engine now.

Yes. Thats a stock height HSR. I used it all last year on the 350. The only differance with it this year is that it has been powdercoated.

Thanks guys. It should run really well. Not only the combo, but with Micks tune I'm hoping for a rocket ship..lol

My machinest cleaned up my port job... When I brought the heads back to him. He just smiled and said I'll clean that up for you.

Pete's hood is a toledo pro I believe. Mine is the moldkraft/greenwood style

Its going. Finally got back out to the garage today. This cold weather hasn't been helping me with motivation.
Got my checker springs on (thanks Pete, the advice worked).
Played around with measuring pushrod length, but Nuts4c4 is gonna stop up tommorow to confirm my measurements. Never done it before so I want to be sure its right.

temporarily threw the distributor on and rotated the engine to get it primed.. Oil is coming through the lifters so I'm getting close to putting it in and wrapping this up.

For those of you following this here's an update

Pushrod measurement is done.
Got around to getting the short block installed. Well almost, took a while to get it lined up with the tranny, got 3 bolts started. Worked very slowly to make sure I wasn't binding anything up. Its almost there, just playing around getting these motor mounts to line up.

Here's some pics

Ok, gave it a love tap an it dropped in. I have the mounts all bolted. Sweet!

Now I have a question.

Engine block is lined up nicely with the tranny, I still have 3 bolts that are started and only put in with my hands.

TC spins nice and free and not yet bolted up to the flex plate. Here's my question
Right now I have about a 1/2" between the TC plate and the flex plate. Am I suppose to just pull the TC forward to meet the flex plate or is there something else?
thanks guys.

thanks guys.
maximum distance between the converter and flex plate should be around .290. if exceeding that you will need to use a spcaer (real grade 8 washers not lowes crap). However, until the trans case is somewhat tight against the block you won't know for sure what you have for distance.......where's Pete ?
Is that duct tape on a paper gasket?

The trans case is nice and tight to the engine block.

So I suppose making spacers out of some scraps pieces of pressure treated is out of the question?...LOL I put the old head gaskets on to protect the deck and then used duct tape to protect the bores, and the plastic to protect that. I didn't want anything in there thats not suppose to be there.

I was thinking if I pull the TC forward to connect then it may not drive the pump in the tranny so that may not work.

The new block and flex plate matched exactly to the old block and flex plate so I'm a bit surprised that I have this amount of space in there.

Gonna try and get a photo of it in just a bit.

Thanks vettemike... now that its a bit warmer I'm ready to roll with this thing. Took a while last night to get everything to line up , the correct angles and such. But just wanted to take my time with it and be sure its right.
