For sale or trade: Brodix B1-Bs Heads with rockers. Never been run. Looking for larger chamber heads. $2600 Obo.

Yessir, I have already done the spring relocation into the frame rails along with a mini tub.

Thanks for all of input guys! Was kicking around the idea of 4 link or ladder bars but I figured if I was to go that far with the fabrication I might as well back half it and that’s not exactly in the budget at the moment...I don’t know how much the car weighs, or any details like that because...

It’s alright, caltracs are a consideration but I’d rather spend my money on something that is proven to work rather than something I’m hearing mixed reviews about. I do understand you can’t just bolt them on out of the box and expect them to work, I don’t mind spending time tuning my suspension...

Hey everybody! Seeking help and advice for a rear suspension set up. Car is a 71 duster, Inboarded springs and narrowed 8 3/4. Engine is a 421; half filled block, 3.5” stroke, 4.380 bore, 14.5-1 compression with b1-bs heads. Plan to run e85 and maybe a single stage of juice. Trans is a th400...

So as far as strengthening the bottom and top end to be able to handle the said "8500" rpm, what all more can i do? The block is already half filled and studded mains. Maybe a girdle? I saw that BCR makes a pretty beefy one along with their main caps that tie into the webbing. As far as the top...

I didnt realize how tight i could actually wind this thing! Lol looks like ill be investing in a darn good valve train along with the MW 270 heads!

Ive searched high and low to try to find another combo using a 3.5" stroke crank to no prevail. So i dont know what this thing will really do when i get it all together! It probably would spin even faster if i left the childs and albert aluminum rods in it that i originally had planned on. But...

Thanks for all the info! I think the 270s are in my near future then, i was just worried about port velocity but they seem to be a very well thought out head. Ive heard a couple guys try to bash them saying that they have valve shrouding issues and couldnt be ported any further because of the...

I dont mind spinning it but dont want to loose out on any low end to mid range grunt its got in it. The cam will eventually be switched to something a tad bigger also.

Thanks Andy! I have been following your 470 build and that thing makes some healthy numbers! The reason im a little leary to use the 270s is i want to be able to produce some decent torque numbers too. And given the rather small cubes of the engine if i went with the mw port wouldnt that put my...

My intake choice will be based on what heads i buy. I do have a polished tunnel ram for a b block...std port but right now im looking for what will work best on the combo and dont mind spending a few bucks on a nice mw port intake or different std port.

Oh, and it will be mostly a track car, maybe see the street to take to work or a car show a few times a year... Also dont mind putting the bottle to it.

Hey all! Im new to this site and thanks for having me! Ive got a 421 short block consisting of: a 72 cold weather 400 block .040 over, half filled, studded mains, bushed lifter bores. 3.5" stroke offset ground 383 crank, 2.2 bbc rod journals. 6.535" manley i beams with .990 wrist pin. And 1.695...
