Re: Offshore pro flo xt knockoff
That particular seller is. You can google "sbc mpfi aluminum intake" and you'll find them on amazon, ebay under similar descriptions.
Good price, even if it needs porting/cleanup. I might buy one just to have before they get sued.

Can't really sue someone in china making it! It looks so much like my pro flo xt it's crazy. Would be interesting to see the quality.

Re: Offshore pro flo xt knockoff
The knock off in my case is better quality than the Edebrock one. Both use the same dumb Ford 4 bolt throttle body flange pattern Edelbrock stupidly uses rather than a GM 4-bolt LS pattern. Edelbrock screwed up on the Proflow manifolds on both the LS and SBC stuff using that stupid bolt pattern rather than the LS 4-bolt. The manifold would be a lot more commonly used if it had a LS 4-bolt flange for a 92mm TB rather than the Ford 4-bolt 90.

Never tried it though.

Re: Offshore pro flo xt knockoff
I wouldn't think it'd matter too much which TB you'd use? The Ford one...the LS one...they're both ugly but functional.

Re: Offshore pro flo xt knockoff
I felt like Ford went from fast idle valve to drive by wire and skipped IAC.

Re: Offshore pro flo xt knockoff
Good question.
I recall '80's V8 having a spacer plate between the TB and the plenum flanges...that spacer plate had the mounting and port/channels for the IAC device.

Re: Offshore pro flo xt knockoff
The irony though is a lot of cheap ECUs like the micro squirt don'
t have iac drivers but do have an idle valve output.

Re: Offshore pro flo xt knockoff
Yep. I was thinking EGR plate, but this pic shows the idle control device on the side of the TB...

Re: Offshore pro flo xt knockoff
this is the way the throttles are on the pro flo. It looks like a weird ls/ford hybrid. I've been really happy w it but IDK what I could replace it with if necessary.

This is the adapter, and they seem to be far enough apart:

Re: Offshore pro flo xt knockoff
Are there any dyno or flow bench results or feedback on use of these manifolds? Do they flow as well as XT? Was thinking of getting on but don’t want to end up with a paper weight. 🤣🤣

Re: Offshore pro flo xt knockoff
Was just wondering if anyone has installed in an engine and actually had dyno or track results. Or even just street driving. 🤔
