Intake for 572 street engine

Post  busta on September 18th 2013, 12:39 am

A friend is gathering parts for a 572 BBF build. Will be a street car. He is tossing up between Edelbrock Victor and Trickflow single plane intakes. He will use a 4500 style dominator. 11-1 type compression, run on pump fuel. Hood clearance not really an issue.

Which would you use and why? Is there something better?

the TFS Mafia intake would be my choice, the victor needs alot of port work for the bigger engines.

OK. Does the TFS need to be port matched to P51 heads? Would you use it out of the box or does it need to be cleaned up? He is basically looking at a bolt together engine for the street with mostly off the shelf parts.

You will still need to do a Light port match, but the pelnum and runners are alot better on the TFS manifold.

What are the differences in the R series and the Track Heat? Obviously height and carb flange. Track heat any good for a 572?

Trach Heat 4150 manifold is to small for a 572" Engine IMO and its for a 4150 carb.

The R manifolds, 1 is the "Mafia Intake" for regular heads and the other is for A460 Race Heads and it will not fit stock style heads.

You say "street" car so you better elaborate upon what exactly you mean.

A once a week "cruise night" and "parking lot car show once in a while" is not most people's definition of a street car.

Around 750 hp and must run on unleaded pump fuel. Mostly a weekend fun car.

He already has an A460 block and a 4.5 crank.

I'd go with the TFS manifold for one simple reason....it'll be good right out of the box. If one manifold was better than the other at 3,500 rpm I'd doubt one could tell the difference due to the lack of traction on the street with a 572" monster.

I would love to see a side by side comparison between the Victor style intake and the Mafia style intake, but in my instance hood clearance IS an issue... so the comparison would be Victor with 1 inch spacer vs Mafia with no spacer... would there be much if any overall HP/TQ difference and where would that difference occur (RPM range as it relates to street driving, meaning 10 extra HP at 7500 means nothing to me if you lose 25 ft/lbs at 3400 RPM)
