Afr chevy 210cc enforcer as-cast I am interested in these, but another review site says "They are listed as "LS1" heads, as they require a minimum 3.900-inch bore, so 4.8L/5.3L-bore engines need not apply" Why would these not work on a 3.800 bore? Can the shrouding be that bad? They come with 2.02/1.60 valves.
How’s it going?
Valve size, esp the intake I think determines this.
GM used 243/799 on 4.8/5.3 but the valves are smaller.
Chamber width on 243/799 btw is 3.9”......
You would do well to round up some GM heads, have a nice valve job done and be set!
Or, you could bore the 5.3 to LS1 size

Slow, but going.
Ah.. Maybe its the chamber width. I have some 862s sitting, but also have some 799s I may just use. When you look at all the money involved, its almost cheaper getting the AFRs.

Those AFR 210s will work GREAT on a 5.3 bored out to 5.7!
Thats what I would do with a 5.3. My friend 64Post on here did that with some
ported 243s and the Cam Motion Titan 4 227/232 113+3 in a Fox mustang with
turbo 350.2800 stall and 3.55s Killer street/strip combo with Excellent daily driver
manners, the AFR 210s would be EVEN better.
Just my .02

You would get a better results going with the 862 have a CNC port , and good vj ....... I would run 1.95 in and 1.57 ex on a 3.8 bore !
