Installing the HO 350 into the 1980 Coupe

Finally, it was time to install the new engine.

First things first, I installed the flywheel clutch and pressure plate onto the engine. For a one-piece rear main seal small block, you need the ‘86 and later flywheel, but it need to fit the small G-body bellhousing.  I found one at Pace Performance that is used on the Camaro, 14088650.

Next, I slipped the clutch fork, throwout bearing and fork boot into the bellhousing.  I used an all-steel Hayes bearing because the freebie included in the clutch kit was partly plastic.  Chevrolet engine blue.

When hunting for a later 350, here is where to look for confirmation…the block casting number is on the other side of the distributor.  Earlier, 2-piece castings have the block casting number on this side.

Next, I set everything up on the curb.  I took off the clean factory grille to avoid disaster.  Chrome is hard to touch up…

Ready to Swing

I pulled the bare block and transmission out and set them aside.  The T-5 was brought out for some comparison photos shown elsewhere in the postings.

I bolted on the Tremec…

Mating the Tremec

I managed to persuade my pregnant wife to join me at the curb.  We brought out the covered swing to provide shade so she could point and laugh…

Say Ahhhh...

The difficulty with installing an engine into a lowered car is that the engine hoist runs into the control arms and frame.  It was necessary to put the front of the car on jackstands.  However, this helped out later when I needed to crawl under and align the transmission crossmember.

Hanging Iron

The engine tilter was a useful addition for this project.  I had to pull off the crank and use a ratchet to clear the lift arm, but it was instrumental in clearing the firewall and radiator header.  I’m glad I had the chance to fit up the crossmember prior to dropping in this motor.

A Peek Though the Grille

Here it is with the hood back on.

A Nearly Whole Car

Done.  Some further parts will add weight to the front and level the stance a bit more.
