360 main caps

[Monaco Man 78]

i just pulled and 88 360 hp block and was wondering if i would be able to use my main caps off my 79 360 engine. or do i have to get the main caps that came with the 88 block. please any help would be great. i left all of the caps for the crank at the salvage yard when i pulled the engine

To save yourself a line bore/hone, I would use the 88 caps.

if you dont use the caps that came with the block you will need to line hone the mains...

and never heard of a 360 hp block....as far as the blocks are concern..they are all the same...

it had a 4 barrel intake factory egr block of plate, all heavy duty the tranny was a non lock up 727

That was prolly the last of the quadrajet 360`s they used in the 1 ton trucks with the dual snorkel air cleaner before they went to TBI.

Still, you need to use the caps off of the block they came off of.

are these heads open or closed chamber, also are they 65cc heads. went to the yard and picked up the main caps, so thats out of the way.

An 88 360 would have open chamber heads. They would have the same 72cc chambers that all other 340/360 heads have. If they are 308 castings they will have a better port shape and would be prefered.

what year of heads have closed chamber design?

i have a pair of smog heads off a 79 360 engine are they the same as the 88 year heads, besides what you mentioned above

You will find that virgin the 340/360 heads up to the closed chamber and magnum heads will CC on the average of 70-72 cc's. They will all with very little work flow the same. Even in stock form you will not notice any difference unless you are getting time slips and the difference will not be as much as you think.

guess i got the pick of the litter the block that i pulled is a 1974 360, the casting number is 3870230-360-4, but the heads are using later style heads used from 76-88 casting number is AAWJ 3769974, what the difference between early style blocks and later style, are there any pros and cons to this block., i need some advice why would they mix heads with a different block, would this affect making a 4.000 stroker crank in this block or is it better.

wonder why it would be in a van?
