ok, I have an 87 d50, I also have a mighty max sport parts car. both are 5 speeds. I was going to take the head off the mighty max (apparently its rebuilt) and do a port/polish on it. I've also been looking at a weber carb kit.
I was also thinking of machining the deck surface of the head to increase compression ratio... is this a plausable mod on this engine? or are the pistons/valves too close? anyone know the stock c/r?
are there any other cheap/free mods to increase performance?
I am also wondering about a posi rear end, what does the mighty max sport come with that makes it sport? does it have a posi? is there a cheap one available?
i'm very new to this engine. appreciate your insight.
