i have a d1ve block ,thinkin of doin 4bolt main conversion using miloden caps , is it worth it ,im on a budget

wanted to do 4bolt main cap conversion on my d1ve block

im on a budget lookin to do a 800-850hp at flywheel
prob gonna use nitrous

but lookin at doin 4bolt main and doin a partial fill of hardblock to bottom of water pump holes
and aybe a valley girdle

i know a A-460 block is ideal , but im not loaded

thanks , any input will be appreciated

this is gonna be a race motor for my mustang track only

Didn't you recently post a question just like this...?

Just my oppinion:

Forget the valley girdle unless you simply like to spend money for ficticious reasons.
Fill the block half way.
Use some main cap straps on the mains with studs.

posted a thing about cost of of getting caps done

what can these blocks handle with 4 bolt center caps and a partial fill ? any ideas?

I've been using a 2 bolt block pushing a little over 800 for 9 years. 1900lb dragster though.

iv used the pro gram caps on a few and have had very good luck , one was well over 1000 hp with nitrous.

x2,and did you check out the thread over in the bar&grill with the nice pic's of a build like your thinken about?caps on a d0ve block would be a good start if you cant swing the A460 now.

If you haven't looked at this thread, take a look. It might change your mind about the D1VE block...:

The A460 block is an investment........glad I made mine years ago.

While that's a very bad and costly problem, how much of that could have been avoided by not using the 4.5 stoke crank and using a 4.3 stroke? I've always heard that you want to avoid the 4.5 crank in a D1 block and it's better suited to a D9 block since it has the longer cylinder skirts. Obviously not saying an a460 block wouldn't have been the better choice, just want to learn something.

Ask Paul Kane,
Im sure he will probably chime in here. Hes pushed a ton of stock parts. He WILL know.

If you have the money to build it twice, you have the money to build the correct way once.
