PA old time drag with question
Friend and I went today. Very cool, mostly flatheads and old bikes racing
I’ll post pics. The question is: is this a newer engine with older heads or can you convert crab or helmet to this?

Andy...It could be either, but I'd guess this one is a '49 or '50 with early heads and '42-'48 fan set-up . DD |

Re: PA old time drag with question
Looks to be a 8BA block with 59AB heads....Cam might have to be replaced to convert to crab or helmet....

Re: PA old time drag with question
It’s the distributor which is weird with old heads.
Either they converterd the crab / Helmet to use a later model distro or they used older heads on later model flathead. Which I doubt would give more horse power for drag.

Re: PA old time drag with question
i did a conversion once, by simply swapping a late cam to an early block.. needed a front cover and obviously the distributor.. most difficult part was keeping the dizzy from moving.. which I accomplished with a simple set screw in the timing cover.

Re: PA old time drag with question
You can install early heads on late blocks and visa-versa (24-stud). The only real difference is the water coolant passages which is a fairly simple modification.

Re: PA old time drag with question
The alternator mounting is kind of scary....
