454 stock markIV block
Parts available now are
2 sets of heads available
359 heads 101-103cc semi -open 2.18 1.8 valves unsure if ported. LARGE oval ports for certain!comparable cfm flow to 781heads
1972 049 heads measured 113cc open 2.06 1.6 valves stock no mods at all.
Holley oem cast iron intake compatible to performer rpm
Holley 750 double pump
Hei ignition
Th 400 transmission with shift kit
Headers
Flowmaster 40's 21/2 out rear
All other parts I need to buy.
The engine needed to be bored .30 over
I need new pistons rings, etc..
My goal would be 500 hp or as close to it as possible
My budget is $2500 all to the machine shop
I can't afford to have work done on the 049 heads plus it seems I have a head start with the 359's with the larger valve and lower compression. I'm guessing a 2500 stall converter I have 3.08 gear ratio now and will leave it for time being
Any advise is greatly appreciated
Confused about buying a flat top or dome piston along with size. how good would the 049 be with a flat or dome piston with no work at all. Càm of course
Is it better to have compression with dome piston and open head or flats with semi open

Thanks guys!!!!!
Building a decent performing big block engine is never going to be dirt cheap but the results can be impressive without spending $4000 plus like most of the magazine articles will suggest,I could rather easily list a well known combo of effective parts that could be used but its been my experience that almost no one will follow the parts list exactly, simply because they will find less expensive parts,and use those,and not one guy in 20 will think there will be a difference in the results. but trust me when I tell you the results will be far different!(thats a bit like substituting 1 cup of salt for one cup of sugar in a cookie recipe, because the two ingredients look similar,and you found salt on sale, then being amazed and confused when the cookies made with the non-listed ingredient don,t come out nearly as good)
nor is it likely the suggested machine work listed would be done correctly, in most cases , simply because machine work tends too cost money and if your not sure whats being done and WHY ITS BEING REQUIRED, it tends to be ignored, so the best route is a quick education in why things are done and whats required, with a bunch of reference material, that you can read through and then decide what YOU CHOOSE TO DO!

BTW, , on BIG BLOCKS the oil pumps and oil filter adapters are different due to the block oil filter recess and rear seals being different
mark iv blocks
mark v blocks
(keep in mind that ALL '91 and later Gen.V and Gen.VI big blocks come with 4-bolt main caps. The two-bolt big blocks are no longer in production
MANY BUT NOT ALL aftermarket head designs have been modified to work on both the early MARK IV 1965-90 and later MARK V & VI blocks 1991-later.)
