Take a look at Dom's 470 (thumperdart), 400 block so it's easier to get into an A body, shorter stronger bores, heavier main bulkhead, reasonable stroke (less stress on block) and goes like a scalded cat. AND he's been whipping that thing forever

We have had ours together for 10 plus years, been as fast as 8.98 with a 200 shot. Without it runs 9.80s all day in a 3,300lb duster without me .. plus about 2,000 miles a year on the street. I used good fasteners good caps and a girdle. It's a 400 base -1 heads small roller, single 4 with a dommy .. haven't had any cap walk problems and I shift it at 6,800 go through the lights at about 6,200 with the 4.30. It is a low comp though at 11 to 1 .. I have freshened it up twice in that time .. go big block you'll love it .. don't get me wrong we run a 340 in the wife's car and it runs good but leaves me wanting more .. her car runs 10.40s and is street driven 67 barracuda.... Good luck with whatever you decide 👍🏻

Build a 470 or 511 with a MW port head, .700+ lift cam and run 8's on a 200 shot. Pretty simple combo if the block doesn't split lol.

One VERY good thing you can do would be to buy a center weighted crank, then add some of the better bandaids like studs, aluminum caps, etc. A center weighted crank puts the balance weights where it is best, at the opposing forces, not making the block carry the loads to other bearings. I run one, and saw improvements in cap walk problems .


Which manufacturers make a centre weighted crank for this application? Also, did you have to run an external pickup with that stroke?

I have no doubt I'd love the torque lol. What size is your engine and whose rotating assembly in it? Thanks for the input!

It may sound stupid, but I want atleast 500"+ if I'm going big block....the part about the block not splitting would be great if it was for certain lol

4.375"x4.25" combo with a 175 shot made 950hp@6000rpm, shut off 1000 rpm below peak hp.

That's 511" of pump gas friendly street motor with less than a .750 lift cam. I'm sure you could do more with a dominator (we used a 4150), larger n20 grind cam (mine was spec'd for the indy t-ram @ .740 gross lift), more compression, etc.

Then you just tell everyone it's Cordoba 400 with a 150 shot and let the good times roll.

Any more details on this combo? What did it run? Heads, compression?

I like your thinking lol

I must say my block has been awesome for what it is and although not super fast, it's been deadly reliable and past 7500 MANY times and is still kickin 15+ years later w/my dumb azz behind the wheel solidly in the 9's n/a...........Happy is an understatement........ boogie beer

Not that large, but my 500" engine uses the early 230 "B" low deck block and the 4.15" stroker kit (really light pistons) 12.4:1 compression.
Hughes CNC ported Max wedge Victor heads, and 0.720" lift cam.
Car is slow, too much power for the stock suspension.
It has the BCR aluminum main caps and 1/2" girdle, but no block fill, and the #8 cylinder was sleeved.

The cost of the main caps/girdle was $800 plus machine work, which varied quite a bit when I called different places. I think machine work may have been around $500?, and I had some quotes over $800. So just that upgrade costs me $1300 on top of the cost of the block and other machine work.
This made me start to look at the cost difference of the aftermarket blocks, but I hear they are hard to come by now?
