ok so im looking into an 89 a guy has for sale for a good price but im leary.

its got 700r4 and 350 but he says it gets hot says he thinks is a weap in the head gasket. so if i got this truck ive got a 400sb i might wanna toss in it.
carbbed of corse i dont think the ecm would like the 400 with all its mods if i used the tbi system. is it a big pain to switch all this crap off or what??

thing worrys me is if it runs hot all the time an he drives it might be a cracked block or head. and the owner might not know it and the price is $1200
ive seen pics of the trucks fixed up and they can look sharp

Have to look at how much to get it looking good like you want and if its worth it. A 350 or 400 with many mods will give the ECM a headache and a carbed truck takes away the fuel mileage and harder to sell to just anybody but thats just my opinion.

And the owner just might know for sure and lead you to believe it's just a gasket fix. Plan on the worst and you won't be dissappointed.
