My son and I just finished a heads and cam change on his 96 LT1 yesterday (took 13 working days) and drove it home. We pulled the engine alone with hood still on and, using a chain swivel bought at ACE Hardware, re-aligning the engine/trans wasn't hard at all. With him up top working the hoist and me down-under, it went pretty smoothly.

We should have sent the PCM off for re-programming when we first began the work, but didn't So we had to drive it home with the stock programming. Naturally the idle was awful, but once moving down the road, the difference was dramatic. We shipped the PCM off to PCMFORLESS today, so the car'll sit until it's returned.


Scorpion 1.7/1.65 RRs fit under the stock covers without any mods needed and valvetrain is as quiet as stock.

Just wanted to share. Good luck in your project. Let me know if I can help.

West Point ROCKS!

My experience with PCMFORLESS was 100% professional. I filled out the online form, sent it with payment, they sent me the adaptor (thats how we do it in these older cars) with instructions and once I got everything right with the engine, it fired right up and idled smooth like it had been running this way for years. Compared to the older distributor cars, it's a bit anticlimactic to just start it up and let it idle. I'm used to playing with the ignition timing for a while to find the perfect balance between smooth idle, easy start, and high revs.

One thing I'll suggest with PCMFORLESS though, if you want any lope in the idle, tell them up front. I didn't think they'd be able to make mine sound as smooth as it is. I like it though, once I get the exhaust back on I may be able to convince some silly ricer that it's stock with a loud exhaust.

It's not a record I can have mine out/back in and on the road in a weekend.

Couple hours to remove it and a couple of hours to put it back in.

These cars are sooooo simple to work on. I never remove the hood.

I was being sarcastic that it took so long. However, you might have the actual record.

I seriously doubt it. I never have grown up help, and my daughters don't want to get greasy or hot so I work solo until its time to operate the engine hoist and then one of them will come out to help operate the jack on the hoist (and they give me about a 15 minute maximum so I've learned to be efficient).

I probably could cut the time in half with grown up help

Got the exhaust back on (what's left of it) in time to take it out on the fourth. I've been driving it around quite a bit, probably put about 300 miles on it already. It's used almost one tank of gas. Seems to average about 22 or 23 mpg highway, depending on speed and conditions, but somewhere around 10-12 in town. Unless of course I'm on the gas, then it's measured in gallons per mile....

I'll be headed to the local 1/8 mile drag strip in Havana this weekend. They've got a wheelstand competition Saturday, but will also be running a regular bracket schedule. Test and tune cars are only guaranteed 3 passes but if I enter either street or sportsman class I'd get at least that anyway between two time trials and first elimination, so I'm planning to race. Hopefully I'll bring back some 7 second time slips, but I'm most concerned with the 60 foot times. Hopefully I can get it into the 1.7s on a pair of bald 275 drag radials without slipping, and without hurting the D36.
