Hi!

Another Idahoan stopping in to say hi!

I'm dreaming of putting together a 7747 or a 7427 for my '78 C20, 292 Turbo 400 factory air, and then to retrofit my '84 LG4 Caprice (bought new, black, loaded inc. F41 susp) to a throttle body system too.

You'll fit in here just fine! Course if you've still got a 1984 Caprice you bought new your giving away your age.

[CorvairGeek]

I was waaayyyy ahead of my time for a young guy when I bought it

By the mid 90s it started attracting attention and now the young guys are interested in it.

Howdy.

Don't let that Caprice get into an urban area. They'll pull the shocks, cut the springs, and put on on 22" wheels before you can get through five blocks.

I think a 292 would be an awesome engine to fuel inject. Does yours have divorced manifold or integral type?

[CorvairGeek]

It is a non-integral head. To the best of my knowledge, the 292 being exclusively a truck engine, never used the intergral head. I've seen lots of 250s that folks thought were 292s but the fuel pump location is different (292 in the middle of the block on the right side, all others the fuel pump is next to the dist.) besides the block being noticeably taller to the trained eye.

I have wondered if the intergral heads actually flowed better than a stock non-intergral, and the exhaust manifold was completely different, but they were so bad (cracking), I would never fool with one.

I would not even think of starting with a '7747, the '7427 is so much better in every way. More capable(E-trans), more types of data, faster, WBO2 and Electric fan integration, better algorithms.

[CorvairGeek]

I appreciate the advice. It appears everything is better about the newer '7427 ECM. I'm cheap and have to see what I can find. Replacing the intake with an Offy will be expensive enough.
