I bought my F100 being told it was fitted with a 272 Y-block by the import company.  It was only this week i've discovered it is actually a 292.

Next year i would like to rebuild it completely, but right now I am preparing to give it a light strip and tidy up ready for this years show season.  

I've set about trying to find out as much as i can relating to the basic spec of the engine in preparation to buy parts etc.

The engine number is B9AE. - 292 or possibly 312.

Head casting as far as i can see is ECL-C  -  292 - Early Thunderbird and Mercury?

Intake Manifold -  ECZ-9425-A  -  I've seen a few posts state that the ECZ-B intake is a good one to have? Can someone tell me why?  Is it just because it accepts a later carb without an adapter..or does it flow better or possess better performance qualities?

The engine i have, is it a decent starting point for a later performance build? Is it worth trying to get different heads? In a perfect world id have a set of aluminium jobbies..No idea if budget will allow that yet come rebuild time.

All and Any input is appreciated.
