Thread: 351W EFI into Classic Rangie

Will do.
Was yours a manual conversion?

C9 - lt95

Wasn't the C4 conversion something they did in the early 80's? I seem to remember someone mentioning that and 727 torqueflite autos back then. I was led to believe you got either, if you wanted an automatic?
Did you end up with the supercharger on it and what type?

No, 84-5 you got a 727, earlier was likely a c9(4) or bw35, the odd t350 floating around also

Never put the blower on, it was a Holley 177

I'll be hoping to put an eaton mps1900 on the ls1 when I fit it to the p38

I remember now, I think it was '79 or '80 that you could get a C4 because it was after our '78 that we learned of the auto being available.
btw there's no such thing as a C9 or 10. That's just something someone made up to describe the different versions but, all it does is confuse everyone.
The holley I've seen adapted to a 351 truck lower with an adapter plate, goes very well I believe. You can get new kits from BH superchargers for Eaton TVS blowers onto both 5.0 and 5.8...beautifully machined too.
I have a P38 transfer kickin around at work, are they much stronger than the RRC one? They look substantially bigger.

Heard the c4 story before, but c9 and c10 denotes change, anyhow

Not sure on p38 case strength to be honest, aside from the vc failing, I've never heard of a failure

Do you know if the VC is the same unit as the classic one? The suggestion has been made that the BW transfer itself is not weak, it's just that the VC failure can be a PITA? I did prefer the BW operation to the LT230 I must say...I think the driveability was better. Of course my adapter will allow the BW to be used again if i want....I think I'll bang that on there for a try when it's on the hoist.

It's different in that the p38 is passenger side drop, classic is drivers side, similarity of internals I don't know, I'm thinking it's strong enough and most viscous failures are 200+k boxes, when mine fails I'll just fit new internals

Im going to load mine with LSD diffs, with the viscous and rear traction control it will limit driver intervention, with a cammed ls1 and intercooled supercharger, 3:1 first gear, I think low range will only be for descents
