3.5 with cast iron heads?

[20-inch-bike]

It seems like a few people are good on this topic here. i am looking for the best over all ideal engine for the money.. if i was to buy a 3.5 for a local wrecking yard and bolt cast heads on "temp" till a intake is made for a carb for aluminum heads... now ill still have a pair of high flowing heads to bolt back on... so to big questions are cast heads on a 3.5 and is there still the same oil pump drive on the 3.5 as the early 2.8? this project is for my sand rail for those wondering why im going old school card and distributor

Same oil pump drive still exists, so that isn't a problem. Heads should bolt right up as well without any issues. Since you'll be running a dist., you won't have to worry about the different crank trigger on the 3500 compared to the earlier engines.

8.08:1 SCR if you use the irons on the 3500 with .060 headgaskets.. and 8.41:1 if you use the .040 headgaskets.


it would run but be a complete dog...

whats the stock compression ratio on a 3.5 bone stock?

sweet on the oil pump drive as long as its the same style length and so forth... and what is the thinest head gasket available?

[IsaacHayes]

9.8:1 on stock 3500. Iron head .040 gaskets are prob thinnest.
