I picked up a 454 out of a 98 Chevy Pick up for Free. I was wondering if it would be any good for a 84 Monte Play toy I take to a 1/8 mile Strip everyonce in a while. Do these need a Vortec intake like small blocks or will a big block intake bolt on these heads? I have found some 502 cams also would this be a decent motor to play with? This will be the first big block I have ever messed with. Thanks
Anyone ever messed with one?
yes i have built many heads are fair they can be made to run just has alot to do with how much money you want to spend and how fast you want to goQuote:

The 502 Cam is a little limited, but certainly satisfactory for a street machine-Comp makes some good grinds for this engine-
Build it-it is in the same Gen VI engine Family as the current 502 and has great potential-
Are the Stock Crank and Rods any Good? I am going to have the crank turned and get some new pistons. Do you have any Cam recommendations? Car isn't driven on the street. How much can a Big Block be bored? Can you reuse roller lifters on a diff cam or do they need replaced like flat tappets do? Thanks for all your help.

As for a Cam, you will need to give us a better understanding of what you want to do with the Car (your expectations), the weight of the Car, Transmission, Converter (if Auto), Rear Gear ratio, Tire Diameter and so on-the more info the better.
P.S.-if your Crank turns out to be bad, or you want to go over 600 h.p., let me know-I have a forged Crank (502-it will fit) that I would let you have pretty reasonably-good luck!
It's just a toy. It's a turbo 350 haven't bought a stall yet was gonna wait on it. I have 4.86's in it now but will probably be changing them. Had a Small Block in it before. It's a 84 Monte SS been gutted except for the drivers seat. I am running 29's on the rear now. Anyone have any suggestions on a 1/8 mile gear for a Big Block? . Thanks
I have a 366 out of a truck that has 40,000 on it, it burnt a hole in a piston can i use the crank and rods out of it in my 454 and make a 427? Thanks
why ? yes it can be done but i would use the truck rods out of the 366 less the 454 has the thumb rods pistons are a bit more for a 427 the 454 to 060 over get you a 468 would work very good .Quote:

well i have built some cast steel cranks 4 1/4 cranks with the speed pro hiper pistons i would go that way496 .but you can use the 366 crank and use 427 pistons if you need a one pc main seal 454 crank i have one fresh truned ready to go that would sell for a good price is the 366 a two pc seal you need to run a seal adapter and a internal damper the truck will not work so hot with car or light truck power water etc brackets
Yeah the 366 is a 1 piece also is why i was gona use it. I have a brand new steel 396 crank still in the gm box i was gonna use but wasn't sure if they made the 2 piece to one piece adapter like they have for small blocks.
yes they do i have used them they work fineQuote:

if you have a 100cc you can use a flat top piston .if you have a dish that should jump it up or a close chamber pistons you may have to trim the chamber out a very small amount to clear how much CR do you want??? at o deck with a flat top you should be at 9.3 . with a close chamber dome piston base off 101cc head you will be at 13.5
Not sure exactly where I am wanting to be on compression. Just wanting to put together a decent motor that will Push a 84 Monte down a 1/8 mile track. I had a 11 to 1 360 Chevy with double humps and was wanting to try a Big Block.
Anyone know some piston part numbers I can use with my Vortec heads on the 454?
call je/srp i have not seen any of them V tech heads from what i know is they have a very small chamber and flow very good . a modifed close chamber piston could work or be rework to fit the head .you never said what CR you need a flat top may work on your 454 .your not building a 427? that 454 flat top will not work in a 427 wrong CH on the piston you will need a small dome piston for the 427 less stroke abit less CR if your looking for hi CR
Gonna just leave it as a 454. Not to concerned on compression ratio will be running race fuel. gonna get pistons and figure out compression then get a cam. Thanks fo rall your help.
