Two SC 61's = trouble

Re: new and old windsors
The blocks are bassically the same,though older blocks are heavier and stronger..Latter models [roller] have reverse rotation water pump due to sirpintine belt..The front timming cover varies but roller motor doesn't have access at front timing cover for fuel pump...But the whole assembly from either late model or early carb will fit on either block..Keep in mind the flat tappet- carb motor has external ballance of 28oz while latter models have 50oz external ballance..So fly/ ballancers wheels cannot be interchanged..
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
