need a little help...

some bills came unfortunitly ......you all now my plans my lx mustang wanting 9.00-9.50 using a glide ect....

getting trickflow a 460 heads and intake for sure ..... but im gonna use my my d1ve block that has 4 bolt cat caps and filled
gonna call lem to get a custom cam .....my BIG thing! is what should i get a 4.3 crank or 4.5 crank
its getting bored .030 over im not putting it on .080 off the bat and have no room for error but ,,,,, wondering in your guys opinions what setup cubic inche wise is the best for my application lookin to do 13.5.1 -14.1 compression but i liked the 545 kit using 4.5 stroke/6.8 rods ect.. but i dk ........ im sorry for posting so many questions on here ...was gonna get a a460 block but recent bills and me having this block already......and my recent loss of my long time friend passing this past week hasnt helped ....

this site rocks and i truly appreciate all your info and help

With that good of a cyl. head there would be no reason not to make the engine big .

If your going to do the small bore stay with the 2.300 valve heads and open them up later. The d1 block will work but IMO I wouldn't waste the money on the caps and just fill it it's cheap, save the money for the better block later. I also like the shorter stroke stuff and a 572 is only a 4.600 bore and a new set of pistons later when you can afford the a460 block.

Just keep it conservitive and the block will live.

the block has caps and half fill already just needs to be machined

Well then get on with it...........

i understand that it needs to be machined lol going .030 over but my main question was what stroke ect ...would be good u guys think

i was gonna do a 545 but also was looking at a 521

Well the old saying goes, theirs no subsitute for cubic inches.... IMO sonic it if it's good punch it .080 and put a 4.5 arm in it and go seeing that you have the caps already. Built a 557 and get the 2.35 valve a460 heads. You'll make 900hp like falling off a log.....

i know what your saying i just thought goin .080 over if i want redo for some reason i have no more room to do anything ....

do i gain alot from a 545 to a 557 with aheads is that 12 more cubes gonna make it or break ? ill do what i gotta do and i know the bigger is usually better

sure you do the valves are unshrouded and I think you will be having to check the valve to cylinder wall clearances very close with the .030 over vs the .080 and beside look at it this way the Block is way cheaper to find than another set of pistons.......

Typical drag motor isn't going to wear out a bore that fast and you can order custom pistons in any bore size like .081 for example...... You typicaly do not need to bore an engine for a freshing up.

If you break someting a scare up a cylinder just sleeve it......

Your going racing, not a 200,000 mile drive.

Exactly. You're buying pistons anyway, go the .080" over and be done with it. The A460 heads like a big bore! It's going to cost you to bore the block either way and it's not going to be that much to go .080" vs. .030". Now get that thing to the machine shop and get to work!

I agree w/you guy's 100%. And imo, as cheap and plentiful as these blocks are. I don't even know if I would take the time or spend the money to put 4 bolt caps on them.

alright you guys ive made my mind up ...instead of me buying heads now ill take my money i had set aside for those a460 trick flows
and im just gonna purchase the a460 block ...thanks guys ......

smart move.
