454 stroker help

Hi guys,
I need help to finish the planning for my 1972, 454 bored 0.100 and cement filed up to the water pump holes.
What are the best set up for max torque?
I will put it in a 1980 Corvette with side pipes.
After some research I came up with this set up? does anyone knows if it would run in 93 octane and be able to keep it cool enough for city and highway drive? Should I supercharge it since it is cement filled?
thanks very much
victor.

4.250 in. Forged crank

If this is something you are intending to cruise alot or drive 45 minutes+ on the highway I think you are going to have cooling problems with that much filler in the block. most times you cannot go above the bottom of the freeze plugs and still keep it cool. The oil coolers are a big help but you are getting outside my knowledge there as to what you can get away with and still be able to cool it. Supercharging it will just make things worse.

11-1 is way too high for pump gas.

NOBODY is going to be able to just tell you what pushrod is correct, these are the very last parts you buy after you measure the correct length at assembly or trial assembly.

Rest of the list looks fine.
Where are you even able to find true L-88 heads?? The real deal will likely cost more than the Brodix heads(unless you already have them or a buddy has them) and the Brodix heads will blow them away power-wise.

IMO what you have don is made a drag 1/4 mile engine, you
couldn't keep that cool city or highway if your name was cool.

vcb, see your other thread. I built you a nice, low-compression motor that should work with the block filler. Never have done the filler on a street motor myself, but if you can't do it with 8.9:1 static compression ratio, then it probably can't be done.

I think this is the way it would have to be too, and I still couldn't guarantee it would stay cool. If you were looking for a "street killer" "outlaw" piece that only gets run 1/2 hour at a time at 50mph then you would be okay I think, but vcb's cam and intake choice doesn't reflect that this is that type of situation.

A bigger,solid roller cam,would probably work better with the added cubes and those heads.

That much block filler won't cool enough to drive on the street, I can darn near assure you. A bodyman over in Ocoee, FL had a roadster w/a 468 that had the block filled as you're describing and w/a Scirocco rad. and water wetter in it, it would just about peg the gage after a run.

Not saying his deal and your deal are the same thing- but that same radiator and a 468 w/o filler could be driven around like a street car. He couldn't believe the difference.

If the rotator is just statically balanced, it still needs to be dynamically balanced, w/the flex/fly and damper included.

The L-88 heads would be good to sell for a good set of aftermarket heads, but I wouldn't build a race engine w/them. Or a street engine either, for that matter.

The p-rods will need to be measured for the exact length when you do the mock-up.

If by intercooler, you mean a water cooled oil cooler, I'd definitely keep the oil air cooled. Add fans and/or ducting, but that engine needs NO additional BTU load placed on the already radically compromised cooling system.

Really, getting another foundation to build an engine from would be the- by far- better choice here. Keep or sell the filled block to someone looking to go drag racing- unless YOU are just using it for racing, as in 100%, not 90/10.

If you decide to run it anyway, you might as well go as radical as you have gears and TC for, cam-wise. The RPM intake needs to go- you're well into single plane territory, IMHO. The 850 will work for now, but you'll be wanting more though, if you get after it w/more cam and gears.

thanks very much guys,

So I should:

Start with a fresh block to keep it cool.

Keep it under 10 compression to run on 93.

Is it worth to do all this in a big block, or 427 SB would achieve almost the same torque with less weight.

The corvette has already a SB.

thanks very much

Going to a BBC in the C3 is going to take a different or highly modded differential/rear suspension, some fairly extensive tranny mods, upgraded cooling system, suspension work- all for a vehicle that will now be a real handful in the twisties.

IMHO, if you want some serious power, yet retain a modicum of handling and "balance" to your 'Vette, you should seriously consider doing a LS swap.

These engines have great aftermarket support, make stupid power w/o reliability problems, weigh a lot less than a BBC w/all the HP/TQ that you could ever want, and can be made to run hard on pump gas.

The same things apply to the tranny, but another good swap would be to go w/the 4L60E/derivative the LS engines come with, beefed to handle whatever the LS puts out. But the suspension wouldn't require anything to speak of, or the cooling system. Packaging isn't a big deal, either.

At least, it's something to consider.

This makes more sense than anything that's been said yet.

What I'd like to know is how many more times are you going to ask the same question?

Those heads are to big for this engine, the cam is to small for the heads and the compression is to high for pump gas.

Lets start with your goals, what you plan to do with the car and how much power you expect. Than we can get you a nice combo built up.
