I understand. Andy did say the M1 4500 worked pretty good out of the box on the TF270's, but obviously the Wilson worked M1 was better and the Wilson worked Indy was better yet or best. I'm really temped to get the M1 4500 and try it. I don't have many options for 4500 B block intakes. If the TF intake was a 4500 it would be a no brainer.

He’ll correct me if I’m wrong, it I’m pretty sure the ootb M1 single plane didn’t get tested on the 270’s.

The 4500 M1 intake worked pretty well with the 270 heads on my 470. The Wilson prepped Indy 400-3 worked better, but the Wilson prepped M1 4500 with standard ports worked really well. This was on the dyno. Going down the track the std port M1 might have been faster. I never tested in a car but it wouldn't surprise me. You should've bought these intakes from me when I sold them. I sold them for about half of what it will cost you to have Wilson port your intake.
The way I understand this was the ootb M1 was good, but the Indy prepped was better with the M1 prepped being the best. The indy ootb was not good.

I was reading through the thread from two years ago where he first tested the 270 heads.
The was no mention at the time, in that thread of the std M1 going on the 270 heads.

Doesn’t mean it didn’t get tried, but no mention of it in a 10 page thread.

If you read through all the articles he did with both the 240 and 270 heads...... the M1 gets sent out for porting while he’s still doing testing with the 240 heads...... and I dont see any mention of an unported M1 after that.

On the first 470 with 240 heads, the porting on the M1 was worth nearly 30hp.

ok, maybe i'm reading it wrong. Only Andy knows. I just ordered an M1 4500 P4529724. Will see if it shows up.

Who had one?

Monicatti. $214

Hopefully they actually have it.

yeah will see. I should get an email by Monday.
