A torque monster is better I think anyway.

Have a good day at work Biff and hope it's a short work day.Happy Friday men ! You know what tomorrow is YEP. December yikes....
That's what I here Fog just hope I can figure out what I need to do.
The rotating Assembly is around $1800 I think, and not sure what all needs to be done
I'm afraid your gonna leave a lot power on the table if you use those J heads on a 400+ ci. engine
even if they have a GOOD port job.

In my experience they can be built to last longer with less stress on components!
Torque is the value of longer strokes!

A friend has a 514 with twins on it. When I asked him what he's putting out he said somewhere between 1200-1400 HP. It sits in a 67 Dart
No J heads U heads is what I have and not sure if there any better or worse.
And when you put the pedal to the floor from a dead stop **** is gonna happen. lol
Driving that would make me **** myself Mark.
Probably gets a few beer cans thrown at him when he cruises the peninsula ehh

Just hearing it start up is scary. A little bit of a rough idle LOL

More from his neighbours I would think haha
Gonna stick with building a 12 second in the 1/4 car not wanting to blast off to the moon. lol

The more HP the faster they break something.
You can do that easily with that puny 340 Fred and still have a smooth Idle. I'm not trying to talk you out of a stroker. I just want you to get the bugger done and driving without breaking the bank.

Have a great evening guys and see who's last but I can almost guarantee I'll be first LOL. Have a great weekend too but be safe.
Sure like that idea BP The body work is gonna cost a butt load and would like to get a little more HP out of it without using nitrous.
You been working on yours? I think we all need a kick in the back side to get our stuff done and sure do appreciate all the input from all you guys.

I want to get 600-650 reliablereliable, low RPM horsepower with 700-800 ftlbs of torque.
Low compression, not a high stall converter very feasible in a stroked RB engine.
I would say that 400 Hp. and 400 ft lbs is possible with a 340 reliably!

I think you are correct. Traction will be the problem to get into the 12's

Small blocks with a stock stroke run good with a bump in compression. Hell I can get a 350 Chevy in the 12 second and faster with 11 to 1 and a set of 2.02 valves on street tires that are bald after 3 passes.
That is a lot of torque I would think. Had a semi that had that kind of HP and even with a load in the tailor weighing 94,000 I could spin the tires if I wasn't careful.
Not sure what the torque rating was.
Can you run 91 octane with 11 to 1? And keep the rpms at 6 grand or less.
That is what I am trying to do and not good at building anything but I can make a good bowl of can chili. lol

i think he would be better off with compression at 10 or lower using Iron cylinder heads.
with aluminum he can push it up, but so is the price of the build and fue!!
i can still get 93 octane here near the east coast. Can you there?

Yes 91 Octane with a 600 CFM Holley and daily driven to work. Lean is mean in smallblocks.

Once he gets the deck done a 10 to 1 popup piston would probably get him the compression he needs. The cam does not need to be wild either. I would need to look up my card but I remember it being around a .450 lift. That car was sick it would melt the tires in 1st and rip em loose in 2nd and 3rd at the strip. It did suck in the 60 foot time because of not sticking 1st gear.
