I'm running a 465 Holley on my mildly built 272, runs great and I haven't touch it since I put it on, over 5 years ago.

point taken re stroker engine
its how i learn

If it's simply a matter of keeping the costs down, then the 600 cfm Holleys are plentiful and reasonably easy to kit.  The nice part about a vacuum secondary carb is that they are self compensating when being put on an engine that's on the small side versus the size of the carb.  If opting for a new carb, then the 525 Street Demon Jr, the 500 cfm Edelbrock, or the 450 cfm List #1848-1 Holley are all suitable carbs for most Y engines.

The Holley 1848-1 is designed for modest-displacement Ford engines.

Stuey: Yes, your correct..however that was on a high performance stroker engine, Kevin just wants to pep up a stocker a bit..so it may or may not be a good choice... ?.

i seem to recollect  Mr Mummert getting good results from from a Summit 4100 replica except the fuel inlet tubes leaked

Further on the Ford/Autolite carb recommendation, best to go with the 1.08 version over the 1.12 according to those that know. Also avoid the later smog models used on big blocks. In comparison tests of several carbs, done by our moderator Ted, the 1.08 scored well, only bested by the later Holley 465cfm.

Good ol' 465 Holley would be fine also [as well as 390, 450] very tuneable.. Buy new , cheap, done!

All great information. I am getting a Z9425B from Marc which will go on the shelf. Until then, I will get a spacer between the intake I have now and the dizzy and hook up my PVC. I have another 292 that I already did the upgrade to an edelbrock and new distributer, but I have never started it. When I get ready to rebuild the 272, I will take the B intake off the shelf, replace the distributer, and have it bored for a 292. Three builds in progress. I also have a little 239 that was running sweet when I picked up the truck. That is going out the door. I hate to scrap it, but I can probably get $100 for it if no one wants it. I will try locally on Craigs list before I scrap it.
