I have a '87 Firebird Formula 305 4bbl. and the only pins that I have are:A, B, C, D, and F. Does anyone know what pin the data stream is on.

I'v been thinking about writing a FAQ on the GM ALDL thing, but it will be a while before I do. I've been collecting the posts on ALDL for about a year. I'll simply put them all together with a few humorous phrases here and there and release it for flaming... I mean constructive criticism. That may be as close to imortality as I can get. Now back to reality...just 476 messages left to read.

Millions have been spent perfecting it. Sure, some greasy mechanic, proped on a shade tree chewing tobaco, is saying "High performance engines need high performance oil flows!" Brings us to fact #2. Most high perf (high reving) engines have a problem of too much oil flow at engine speeds above the original limit. The winning racers actually restrict the oil flows or go to a wet sump design to help manage the resulting high flows. Fact #3. You can't increase oil flow unless you increase pressure also, assuming you don't open bearing clearences. Sure, the slick salesman with the cheap leasure suite is saying "Increase the bearing clearences man...jack up the oil flow and pressure and F L O A T the crank on a bed of oil and she'll last forever...even at 12,000rpm. If they didn't tell you this, how could they convince you to buy their higher priced hi-perf parts. Check out HP book's "How to hotrod the smallblock chevy" they may have a ford BB version. This book should be titled "what parts not to waste your money on" very entertaining with testimonies from WINNING racers. You would be surprised at what works and what doesn't. I know what you're thinking Cloud, I've been there and done that with lots of "hi-perf junk" to prove it. BTW, racers used to put the BB pump in the SB to reduce distributer chatter, the BB pump has more teeth, hence less pronounced chatter. All to have better spark timing consistency, which gives consistant power. Hope this helps your cognative dissonance.

For the budget minded cynic, it would be cheaper to just buy HotRod mag, then do the opposite of everything they say ;-) JD ------------------------------ From: Jim Davies Date: Fri, 13 Dec 1996 21:35:16 -0800 (PST) Subject: Re: oil pumps (not efi) On Fri, 13 Dec 1996, George M.

It fits, and its smoother, but it can also pump your pan dry at high revs...oil in the valve covers does not help the crank much ;-( JD ------------------------------ End of DIY_EFI Digest V1 #382 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
