454 Big Block Chevy Engine (BBC) | engine, engine parts | Calgary | Kijiji go get this. that way you won't need a block cuz your block now knows there is a spare to replace it. Those bores look good. This is a low mileage engine

Ahh Crap! gen 5 block mark 4 heads. sometimes mismatch at the deck can cause water leaks. what part number head gaskets did you get? I think the newer ones take care of this issue.

head gasket i got is felpro 8523 pt-1. I saw that whole engine for sale - are you saying the heads on that look good and will fit my block and exhaust manifolds? And if I need a block that the block will also worek for me?

I'll send the guy a text - thx. Also here is the link for the 049/781 heads for $300 asking (454 BBC Heads - Cleaning out parts | engine, engine parts | Calgary | Kijiji) - what do you think?

Called Foothills Mech - their parts dept is closed until Monday. Looked up Mortec on google - nothing like that in Calgary?

The guy with the 454 engine replied - said he would recommend machining heads but valves did not leak. After a few more texts, he said they do not appear to have a low spot but he never checked. If I go out and bring a stright edge and feeler and check. I asked about the intake - he said he thinks it was good but said he would also recommend to replace it? What type of heads are those on the whole engine - are they an improvement over my peanut heads? Will my existing intake work for these in case his intake is bad? I asked what he would take if I came out - he replied asking what I'd pay if I came out today - so he is negotiable - thinking of offering $200 or $250 if this will work for me?

Still waiting for the other guy to get back to me too,. Thnaks

403 277 0101. I talked to them yesterday. they have your exh gaskets. ask them if they have fel pro 1037 head gaskets. they work for your block and the older head. that 454 block needs a different flywheel to be used in place of yours. the heads are same combustion chamber and valve size. better intake ports. they work with your intake manifold and gasket. they are the same as one of the 2 you are looking at for 300. if that guy will take 300 for that 454...GO GET IT!!! even if you aren't using the heads. it is Mopac. and they have the 1037 head gaskets but 68 bucks each.

So if I understand right, that block would not work for me without major work, so really the only value from that engine (for me) would be the heads and possibly the intake - is that right? If right, are those heads good/better than my peanut heads, and will they work with my existing block and intake? Based on past replies I think so but only if I get those other head gaskets (1037) - are the head gasket I got the wrong type??? Being that only the heads (and possibly intake) would be any good for me, what is a good price to get the whole engine at (or maybe I'll just offer to buy the heads - what is a good price).

I called Mopac - they are a national new car parts retailer - they want $2500 for a pair of heads with the valves in them - ouch - can't do that.

Thanks

DNA, the heads I pointed you to earlier are 781's. A very good head for your motor, they are large oval port MK IV heads. These heads are a huge improvement from your "peanut" heads. New rebuild with 0 hours means no valve work or resurfacing required. These were/are desirable heads for the 454. Everything from your motor will fit perfectly with correct head gaskets.
Put them both on and your motor will run better than ever before. Assuming that your block is not blown out like your head was.

They look good but are 10 hr round trip not including delays with border. I'll keep them in mind. I did find those 049/781 combos locally for $300 which comes with chrome covers, starter, etc, etc. Sounds like the 049/781 are a good head.

Thanks

The other 454, after rebuild is a drop in replacement for yours except for having to get a older style flywheel. 25 bucks used. 100 new. Those are also a matching set of 781 heads. You don't get chrome valve covers. But you get a good standard bore 454 block-crank-pistons. You could hone and replace rings and rod bearings and have a "rebuilt" spare sitting in the garage. Tell him 300 if he throws in the engine stand.
