Ayuh,.... Those manifolds don't even match,.....

Hard to believe you rebuilt the motor, yet yer puttin' used, mismatched manifolds on 'em...

I don't see many Crusaders, so I'm guessin' the 270s are SBCs,..??

yep sbc 350 cid. and yes they are used but in great condition and both fit 350 sbc. the black are off a merc 350, a buddy upgraded to ss. they were a gift. the center rise conversion kit for my engines show the exact same manni's. @$1600. the others are also show as compatible in plu search. risers are shot mannifolds are salvagable. kinda tapped out after two motor rebuils, one tranny rebuild, starers, alt, water pumps, ect. So if i am able to use these and convert to a better system{log vs. center} with what i have less the small stuff, then i feel like i need to at least research and give it some consideration. thanks

I have never had any luck getting the plugs out of used manifolds to set up closed cooling. Also this setup will be several inches taller.
