if you are going that route moddifying the intake to accept the TPI tthrottle body might be difficult at best. they are too different in size/shape.
I'd suggest getting a stock round maf and adapting the pin outs to the new MAF.

You'll need to adopt a tunning program anyway for this to run.. With the new MAF you can adjust the volts to flow gm/sec with the software.

I'm with raid though that this will be way too much intake for idle operations on anything short of a 383.

I've seen a few of those Edelbrock swaps - not too impressed considering some of the fitment issues and cost involved.

I'm not convinced that intake is too large for the stock engine.


Just a dang shame the new Pro-Flow wasn't designed in consideration of the C4 hood issues.

Im running a 395 Ci motor with big mouth intake. and 58MM TB. Stock the butterflys were open in order for it to idle-- now they are closed and base idle is controlled solely by the IAC. That means no matter how I tried the tune I can't get it to idle below 900 RPM without it hunting using the IAC as the method of air flow at idle...

Is not currently listed but Intake Elbows.com used to make a 4 bbl hat that dropped a TPI/ LTX TB down to same level as TPI one

shot AAron an email-- they only build for round throttle bodies not our stock TPI
