if u r a boat mechanic please explain

[aussie]

well thamnls spares just dont want to go the wrong way about it

i have to options buy that 302 windsor of ebay and hope it fits without too much trouble and rebuild it first

the next one is buy a edelbrock preformer head with the larger chambers fit the rollers and head comes complete with studs and rollers i was going to go for a 1.8 rocker arm and mod the manifold for a 600 cfm vac look may even pull the engine down and rering ti and get the cam ground to a mild solid but will it all be worth it in the end

i dont mind if i have to spend money in the end it will be a better boat it working out which way to go
