I have a 2 bolt main 330hp 454 with around 300 hours on it. How much is it worth as a long block? It has large oval heads and has been bored .020 over.

I might be interested if the price is right.....I need a short block

i already have somebody interested in it. I need to know how much is a fair price for it!!!!

The longer its sits in my garage the more appealing a BBC honda civic sounds........

It has a 2 bolt main?????
Both of my 330's were 4 bolt main blocks
You sure Puder?
does not sound right at all.

unless it has 2 invisible bolts next to ethvisible ones, its a 2 bolt main block.

1987 454 "mag" AKA bone stock 330 but it does have the large ovals heads.

I have a 96 454 300hp carbed and was under the impression that I had two bolt mains. But after purchasing Dennis Moore's big block book, it would appear that I have four bolt mains..

Should I also assume that I definitely have cast pistons and a cast crank ??

Jay-son, I was really hoping you would get your motors dyno-ed, so I could do the same thing you did you to your motors to mine.

I am on the fence about modifying my current motor or going with a crate or used turn key, and then sell my current motor for hopefully 1,500 - 2,000

I'm basically looking for minimum of 425hp..

Yo bro!!!!
Mine were easy to do
No dyno sheet but approximately 480-490 HP
4 bolt main block
punched .030 over
New 9.5:1 pistons
new crane cam and lifters, double roller chain
Heads large oval ported and polished and port matched to the performer intakes. (subsequently intakes were ported a minor bit to match heads)
and dry exhaust
why go extra mile to get a whole long block when you have a good one right in front of you?
Granted easier, yank one, and dump in new one and your boating again, I get that part, but if you do it in the fall, just take yours out, send it out, let engine place have it for a few months and can work on it at their leisure
early spring, dump it back in and your ready to rock
Just a suggestion

I'm thinking $800. Yea, it's not much, but nobody wants 454's, much less a 2 bolt 330. You may actually have better luck selling it on e-bay or one of the drag race sites. There a 454-even a two bolt is pretty hot stuff.

Well, thats the plan right now, just wasn't sure the cast crank could handle 5,000 rpm's.

I was thinking of going with cam, heads, pistons, intake, carb, and whatever I end up with than so be it.

Just wanna do things RIGHT !!! so no problems down the road..

Hot-boat said he would help me pull the motor in the fall and put it back in the spring. I want to start getting opinions on heads, cam, pistons, valves, carb, so I can be sure of what i'll be doing in the fall..

THe exhaust,,,, I thought my stock exhaust would be o.k. to 425-450 hp ??. If not thats going to add A LOT to the cost..

What did it end up costing you per motor ??, remember I only need to do one..
