Blower Alert!
 

See this ad.

It looks like the smaller one (144) but, the bearing plate and snout might be the same???

I don't think the endplate is the same, but I'd ask him to measure the shaft housing. I think that will probably work.

Bummer.

I found this one before, which looks like a 174, but he wants $1,500 for the whole thing (including the extra Chevy intake). I'd seriously consider the turbo for up to about $1,300 at that point. pppssssSSSST.

Ben, have you contacted Holley directly? I was on their website checking to see if it would have info on the 144 case compared to the 174 case and found that they sell the bearing plates for their other blowers. I couldn't find any specifics for the 144/174 question I had but did find that the nose assembly is the same. I believe the only difference between the 144 and 174 case was that the 174 was longer which gave it the larger ci.

I'll call them tomorrow. I just found this blower after 5 today. That's kind of what I was hoping, that the larger displacement was a function of length and the front of the blower was the same. :huh:

Confirmed 144. Let's see what Holley says.

I talked to the Truck 4wd fab boys last night. You can weld cast aluim---BUT it will warp if not done correctly. There is a guy in my shop complex that should be able to do it. BUT!!! he crushed three fingers a day ago. Timing is everything.:(

Booh
 

Holley says the 144 and 174 bearing plate and snout are NOT interchangeable. Unfortunately I was in a hurry so I couldn't ask why, but they said no. :(

I didn't think they were. Did they say whether the shaft housing was interchangeable?
