[akrapovic]

I dropped by my motor shop and my motor is coming together. Short block is being assembled just waiting on heads. Woo hoo!!!

Lets get some specs on that Badboy :D You gonna have Billy dyno it when its done?

[akrapovic]

It's a procharged motor wet sump motor. I'm going to run a D1SC with the helical gear set. Mild cam so it's hopefully somewhat of a sleeper when it's idling. Wiseco pistons, K1 rods, ls7 heads with upgraded valves/springs. Fast 102 intake. Goals for boost are about 15lbs, we'll see depending on how much the motor makes on the dyno NA. Goal is 900hp hopefully a bit more. Taking a page from the ls9 and going with piston squirters. The car is a 69 camaro with a T56 from D&D.

What kind of valves and springs are you using?

[akrapovic]

Stainless int and inconnel exh. Stock sizes. I'll be running PAC springs.

Motor porn. :D

[tones2SS]

Very nice indeed. That is going to be one beast of an engine. I bet you hit that goal of 900 HP.
Good luck and keep us posted!:thumbsup: :cheers:

Here are the piston squirters. Side note, if anybody is looking for these for an LS7 or RHS block I have an extra set.

Yes they will be doing the break in on the engine dyno. Hopefully Mid December!

my understanding is that the inconel is used in blower application on the exh side due to it ability to handle increased heat. Pretty common actually. please keep in mind that I'm no engine builder. I'll ask the guys at motor city speed. when it was explained to me by billy he mentioned several motors that he built that were similar to mine when he was building motors for wheel to wheel. also apparently the formula 1 cars use them bc their ability to handle extreme temps.

Everthing you said is correct. Inconnel works better for extreme duty like blowers and boats. Blowers due to heat, and boats due to higher RPM/always on...

How much do you want for the squirters?

[JamesJ]

I am using inconnel exh as well on my blower motor...

[67ragtp]

Does all the factory LS7 blocks have the provisions to install those squirters? Or is special machining required?

Thanks Rich

[akrapovic]

Special machining is required. It wasnt a big deal for mine. Tap threaded hole into oil passage and also provision for locating pin.

i never drove a ls7 but had a few ls6 cars and they were really nice engines.im jellous cause my new camaro build is just a small block to start off.money issues was the culprit on that one.your engine is gonna be sweet.:cheers:
