Anyone know what other problems might show up?
Do I need to drill the heads or block?
Would windsor gaskets be used or clevo gaskets?
Could I drill the outlets into the front of the heads? If so would a -12 outlet be enough flow.
Any info would be of a great help
Hey Ltd351 my engine is a windsor with clevo heads except the 3v CHI the main things were to obviously have ur canted pistons for the valve relief, we used the cleveland head gaskets and from memory i think we drilled the block to match the clevo gasket (ill speak to my mechanic to confirm its been a while cant remember for sure) we had to use double manifold gaskets (which we glued together) to get the TFC manifold to sit right, but the manifold had to be a custom manifold at the time as TFC didnt make manifolds to suit (not because of the provision for water passage but because the base of the manifold for a cleveland is different to windsor) as for the heads the holes were blocked up and a new passage on the front of the head close to were the alternator bracket bolts to, and SQP made a custom thermostat housing to suit. another thing is im not sure what vehicle your putting the engine into but because the windsor block has a narrower taller V the extractors dont fit through the original gearbox cross member so we had to have a custom one made and bash in a little of the bottom pan to get it to fit (it was bitch to get the extractors on) hope that helps good luck.
p.s. ive got a comp cams solid roller cam for sale to suit a 351W 248/254 duration @ 50 670though lift with 1.73 rocker with matching springs, collets, and retainers.
