The iron block has the advantage of not having head gasket problems. For every all bore sucess I hear about there are two that had head gasket sealing issues. The weight difference is a factor but so is the price difference. You just have to weigh the pros and cons and decide what is right for your goals and pocket book.

Mike I tried to purchase Allans longblock a while back and I do not want to tell you what he said.. I never go to the track.. Going 346ci solid roller would bring the price up to all bore long block prices.. I have rec'd several prices, but Futral have given me the best price.. The only shop that beat his 397ci alum price did not recommend spraying their shortblock with anything more than a hundred shot.. Going Alum would be my first choice, but I like to pay cash for everything. That would require a longer downtime. The holidays are coming up and I have already committed to spending money on family. I cant even start to think about sending money out for my new build until after X-mas.

I'm wanting CI's, but is the 24 additional CI's worth the weight? How much does the additional bore help head flow...anyone play with some heads on a flowbench to see?? I can't afford to do a 4" stroked motor, so I'm sticking with the stock crank. I'm just building a NA motor, something that can handle 7000rpm.

Vince, I would stick stock cubes and have another forged bottom end done up. Unless you are going to get a crank that iron block would be useless. Its not a 70lb difference either. Try 90

BTW, 9s arent fast enough for ya?? Allan and I are hitting 9s with our lil 348s

Goodluck with whatever you decide man, and sorry to hear about this motor coming apart on you. Hope to still meet you at the Southern Shootout

You MAY want to consult with Joe Prince on this. I WAS supposed to build an Alum block 409. It was going to have the Darton wet sleeve @ 4.125 with the TSP offset 3.822 which is 409. The rods are Carillo and are only able to be used with specific journals. TSP has not been able to get me or JPR an offset crank for nearly 5 1/2 months now. We sent them the money and the stocker as a core, but to date no crank. I got tired of waiting and ordered a callies 4.00 to make a 427. RIGHT NOW Joe has the pistons for this combo in his garage. If TSP ever gets the rods and crank sent out, Joe MAY want to help you out. It is worth a phonecall. At worst maybe you could get the pistons from Joe for a good price. Good Luck with whatever setup you go with. Bear

I would have to go to the track to run 9's.. I am sure your forged 348ci shortblock Ron cost more than the usual 3k forged shortblock. No matter what I need torque.. I have not seen a 346ci torque monster yet.. Most of my races on the street are NA.. Yes I do have nitrous now, but I want to be able to say NOW I am spraying you to show them the difference

I hear ya buddy. GO big, I hope to one day

And my shortblock isnt anything special, just some coatings and sutds here and there

Ron should post some of his old graphs when he first got his car. That lil red POS made more TQ below 4200 than any Hydro 346 LS1 to date.......Although he probably won't admit that now since he's bashed his boys so much

Rons car made torque?? I can produce more torque using a wrench..

Ron@Vengeance

LMFAO.... OUCH.... Yea my RP setup actually made some bottom end back in the day. Im lookin at the graph now and I had 390 ftlbs at 3000RPM. Held 400 ftlbs untilright around 5200 and horsepower carried over to 6500 @ 405rwhp. Nice flat line graph basically. Won many street races with this power. It didnt last long though. RP POS blew up and never made the same #s it did before.

That was the best curve I have ever seen on a heads/cam car....

Vince, a 409 ci TT is calling your name

I know how you feel.. Thats why I am rebuilding.. It would be easy to build a 348ci, but how many of them do I have to build? Yes I could probably spray the **** out of it. I need a tq monster NA and something that can take a 2 stage nitrous kit.. I might even consider a 370ci Alum to get the tq.. Would I have to change the sleeves with a 370ci Alum?

so again, why is the 382" all stroke a problem here for your goals? and i wouldnt be affraid to hit it with a DP 250 shot easily since there are no sleave issues. true you wouldnt have the hp on motor compared to the bigger bores, but oh well.

Bear are u tellin me u still havent gotten your setup done yet?TSP better get there heads outta there *** and send u the rods and extra parts they owe u.

Vince I'd build a 348CI.All Forged with a killer set of LS6 heads/solid roller.Buzz it to 7500 and lay waste to these big motor guys like Futral does with his car

Just kiddin,Build the biggest motor u can afford.For me it was a rebuilt budget 346 with good rod bolts, rings,bearings.

Good luck.....

Vince, after building four 346ci shortblocks for my car, I would definitely recommend going bigger. Torque is what makes a car fun to drive... and that's where the cubic inches come into play. It just so easy to build a streetable, big cube motor. It is a little more money, but I feel it is well spent.

Mike K.

Vince I also say go bigger, but you already know my opinion.

Vince, I have a brand new 4.125 sleeved LS6 block, JE custom pistons and Lunati 4.00" crank to make 427 all for $4600, I am saving up for a C5R block. Or I may just see how many stock blocks I can break, so far none. I would not go for the iron block, your too heavy already. You could have Brandon finish a set of our new Judson 6.0 heads and have something awesome. Good luck.

Decisions, decisions...

CHRISPY

I would be wary of large hits of spray or boost on a .060 iron block.

You need to sonic test for wall thickness and many of the blocks can't go that big due to core shift. I would just do a cleanup on the stock bore 4 inchs and go with a 4 inch stroke crank. That with the big headstuds/good gaskets and all good internal parts will handle a 400 shot of spray pretty safely. 409ci and with a great sets of heads and cam 500RWHP NA and similar torque would be fairly easily obtained. Never have to worry about dropped sleeves etc and you'll get multiple servicable overbores from it easily.
Cheers,
Chris

Yeah 370's are cheaper abd you can go with a little bigger/better heads, but it isn't worth it unless you're going for big boost or spray. (Note the the big FI guys have alum motors: Harlan, PSJ, Raymer, etc) Heck even the big spray guys like ARE are still using an alum block. I say if you're planning on going FI or spray build a forged 348 like most of the people on the board, just my .02.

Where are your time slips? I ll bet you $100 my 370 will dyno about the same as your 388, (I dont think your still @ 511 on your 230 down grade cam is it?) you know I like to hussell (flames). By the way how is your new head gaskets doing, no leaks yet? So when are you going to the track, I want run my 450rwhp to your 511 and my 100lbs heavier car against your dyno queen.

I had alum. block it would leak, tryied anything possible, didnt work. But my iron block had no problems what so ever. Ask those big bore alum guys, if that was their only block, or they had to swap couple before one worked. I am sure one out of three leaks, except darton, c5r blocks. By the way I had my motor over year now with almost 20K miles on it, and the thing is, keeps on running faster. I ll be down the local tracks for some new numbers.
