**600hp sbm block limit? Or is it bs!!**

Spending all that money and not buying a good block is foolish.

They may live but bet all you have your ring seal is compromised, you have to run excess clearances because the main tunnel is moving all over the place, head gasket sealing is also problematic.

I guess the entire world is stupid buying upgraded blocks. I can’t count the number of split bores, blown out main lines, compromised head gaskets and shitty ring seal with factory locks on 550-600 hp stuff.

Just because it hasn’t shat itself all over the ground doesn’t mean it’s right.

Running production blocks with power levels over about 550 hp is just not financially smart. BTDT. Still see it to this day. And not just on Chrysler ****. Got a BBC in the shop, stock block. Guy says it made 650 with a 250 shot. I don’t know that because I didn’t want to run it over a dyno before I took it apart to see where it was since he pulled it several years ago.

I took it apart and he killed the top rings, blew the bores out of it (took .0065 to clean it up and it still isn’t very purdy), knocked the head gaskets out, and scuffed 3 pistons and was getting after the other 5.

All of that is 100% related to his flexible block at that power level. The pistons went in on the high side of clearance and he was still getting after them. That means the bores are moving all over hell.

Im going to fix it as best I can, put it on the pump and tune it and see if he can get a year out of it. I told him it was block time, but he doesnt have the money for it now, but he has the money to pay me and kick the cam down the road. Spending bad money after bad money.

Just plain stupid. Being a penny pinching miser isn’t a smart move doing this type of stuff.

All I know is mine has been running for many years, probably at least 10 and I drive the wheels off of it. I usually run it NA but the bottle was always hot on the street. Ive smacked it so many times running 91 octane main fuel and a separate fuel system for the nitrous running VP110 on a 300hit right out of the hole. I am conservative as well on the tune. This combo has never ever been freshened up yet. It has a Solid Roller in it as well and I have only had to adjust the valves 2 times in its life and it revs clean and Ive revved it 7400 RPM and it likes it.

I do however change the oil alot. More than most would. I use 5 quarts VR-1 30wt and a bottle of Lucas. I also have emd holes that squirt on the timing chain as well as a small EMD hole in the pushrods for direct oiling at the cup & ball. This is an LA shaft rocker build. Small trixxx makes things live. The pushrods are from Manton and the rockers are the stainless old PRW models. This combo obviously works well.

I do run a Vacuum Pump from GZ Motorsports. It sees 18in Vac driving down the freeway. That right there we could start another big *** argument! I have the raw data from an end user... ME! And YES it lives! Maybe I will start that thread now! Lol

And YES I am a Ritter owner. I am building almost the exact engine that turbodart68 is running except I am using a different head. I am almost done with a set of Brett Miller W8's Power Adder CNC Program. The seats, guides and valves are getting done as I type this.
