Currently my '67 is running a LM7 SBE, stock L99 heads, a Capizzi cam grind, ARP hardware and a Melling oil pump. My long term plan has been to build a forged LC9 and to run aftermarket heads.

I've been working with the following industry players for an all-forged boost engine that is getting built this year:

• Summit Racing (www.summitracing.com)
• FastTimes Motorworks (www.fasttimesmotorworks.com)
• Jon Capizzi Racing (www.capizziautomotive.com)

Here is the list of parts that will be used. I'm still updating and adding to the list, so it's not complete yet:

I plan to reuse my Holley 302-2 oil pan and Holley High Ram intake.
The block is over with Graham Jones @ FastTimes. He determined that we are good with a .005 over bore which was going to effect the piston selection.

I kicked back and forth staying stock crank but the one in the builder block was not usable so that was not even an option.

Again this is a parts list in progress, I'll note when it's been edited.

 

Very cool! Trying to stay within a certain $ budget or anything?

 

Yeah I'm not sure what the final tally would be, I plan to figure that out and share it at the end. I figured that Summit would be the best bet for prices and they carry quality stuff so I couldn't go wrong. There are better cylinder heads but they get really pricey.

 

Makes sense!

 

What's the power goal John ? What sort of cam specs? Just curious as it's probably over anything I'm prepared to do. Sounds pretty stout!!

 

Surprised your not going to give Summit a chance on the cam since the rest of the parts are from them. What's the boost coming from?

 

I'd like the longblock to support 1100rwhp reliably, I wanted to say 1200rwhp but I don't wantt to get out of control.

Right now the car has a billet wheel FIS BW 95/96 ddn.

 

i have had good luck with the btr small bore "ls9" head gasket

 

John, has the builder brought up filling the block to the water holes? If not, I guess they believe the LC9 is capable of staying together at that level?

Seems quite impressive for an aluminum block… I have no first hand experience with the LC9, but we pushed an LSA to around 1200 crank.

Best of success to you!

 

Not planning to half or full fill the block.

Jon Capizzi has pushed an unfilled LC9 to 4.20s with safe tuning.

 

You plan on the same RPMs as him?

 

I don't plan to buzz mine higher than about 8000, and I don't have plans to run 4.20s'.

 

Very cool John. Best of success with it!

 

Yet.......

 

Supposedly my SBE and this planned built combo will run up over 8000 but I'm not at a point where I know what it wants.

 

Sounds like a solid build. Should work out great

 

I'm gonna guess your turbo will need a bigger exhaust wheel to run efficiently up into the 8000+ rpm range.

 

The original owner of this 85/96 spun it over 8000 and did well with it (7.72@174, 2900 raceweight).

 

Ah okay, I was think of Scott MacDonald who ran a 5.3 and saw some pretty significant gains by moving to the bigger exhaust wheel.
Can't wait to see some results!

 

Updated with more part numbers. Changed the pushrod part number to longer ones.
