Karl's 1979 242-T5

What are the plans after the engine is apart?

Mostly just a clean up and inspection for the bottom end. The head is getting ported and it's getting (possibly reground) GLT cams.

your giving $500 a run for his money on crazy tear down times

see what happens when your left alone

Nothing crazy? Cool. I like to see a total tear down for a minor checkup. Keep up the good work.

wow, this would be a perfect time for rods that dont bend...

or bends that don't rod...

cool vid, why the transmission removal instead of pulling it out as an entire package??

It's a pretty tight fit. The engine wont come out without taking the bellhousing off first.

If I could afford a set right now, sure. Want to send me an RSI gift cert?

Fantastic work man. Post a picture of that indestructible whiteblock bottom end. The crank supporting is so tough looking in those motors.

Got the motor ready to drop back in:

Just kidding, I wish.

Spent all day scooping sewage and replacing the ejector pump in the basement, so I only got a few hours in the garage.

Down to the shortblock:

I inspected the sleeves, and they all look good, no apparent cracks anywhere. Crosshatch also looks good:

I'll get some photos up tomorrow after I tear the bottom end down.

lookin good man, jealous of the work your getting done, looking good!

I am sure you are an inspiration to many people on this board that dream about a swap like this. Keep it up !!

Thanks guys. I appreciate it!

Spent an hour today making a ****ty valve spring compressor tool:

Then spent another couple of hours pulling the valvetrain out and degreasing the head:

Going to Home Depot or something tomorrow to get one of those little boxes with compartments to store all that crap.

Are you porting the head yourself or are you sending it out? What are the specs on the cam grind? Total lift mm and overlap?

I'm porting it myself. I haven't nailed any cam specs down, but I've been looking at something like 10-11mm of lift, ~320 degrees of measured duration, and an LSA of ~100 degrees.

get old egg cartons. works the charm.

Has anyone checked what the max cam lift is on these engines? (clay or toosie roll in the cylinder) I haven't been able to find much info. on aftermarket cams for these engines. 320 duration & an LSA of 100 are up there @ NA race cam specs.

But, I'm wondering if those numbers aren't a little extreme for a high boost application, I thought with high boost you wanted to dial the overlap back? My book doesn't list the stock duration or overlap on the DOHC cams, so maybe they aren't that radical compared to stock?

I had a long reply typed out but then the power went out for a second or two.

Enem's 5 pot cams lift almost 10mm. I'm lowering the compression anyway, so I should have some extra leeway. There are apparently guys making in excess of 500hp on the cam spec I mentioned, so I'm not worried about it. Regrinds are cheap, and GLT cams are cheaper.
