🔧 BUILD Boost for the Masses - LC9 longblock build

[Pro Stock John]

As most know I have a 1967 Camaro with a driveline swap. Currently it runs a gen 3 LM7 SBE, stock L99 heads, a Capizzi cam grind, ARP hardware and a Melling oil pump. The rest of the combo includes a FIS billet wheel 85/96 turbo, Shearer air=air intercooler and all of the necessary parts to support this boost combo.

I have no idea how many miles are on the engine parts lol. 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 gettting 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:

GM LC9 engine block, bored .005 over
TFS-30619991 TFS 220 Cylinder Heads
SUM-180LS362224x Pro LS 3.622 crank
SUM-LS6125927 Pro LS 6.125 H-Beam rods with ARP 2000’s
SUM-2999273785-7 Pistons
ARP-234-4317 Head studs
ARP-234-5608 Main Studs
AAF-ALL87024 Cylinder head dowels
NAL-12575329 Chevy Performance O.E. 5.3L bore replacement head gaskets
TFS-21407500 pushrods
SUM-HTLSKIT2 Delphi LS7 lifter and tray kit
NAL-12561513 Long Crank Key
SUM-161000 Short Crank Key
CLE-SH2125S Cam Bearings
MEL-10295 Melling Oil pump
SUM-G1585 LS Engine Hardware Kit / Plugs Dumbbell/ Side Bolts
SUM-G2627 Cam Change Gasket kt

ARP-200-8683 Windage Tray Nuts
ARP-671-1002 Oil pump Bolts
ICB-551432 Timing Cover bolts
SUM ___ LS engine diaper

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.

What are your HP goals out of this build?

 

[IceCreamAssassin]

Graham does great work, look forward to hearing all about this.

Shawn, 1100rwhp

Surprised to see run of the mill ls7 style lifters.

Excited to see build pics! That 67 is a great looking car.

 

[Pro Stock John]

Yeah I've been pondering lifters. Capizzi never had an LS7 lifter failure but thinks something like a Johnson link bar lifter would be safer. I need to see what the pricing and availability is for both.

 

[Boostie]

Sell me the old 5.3 for cheap lol I have also been considering building a backup motor for my car. I dont know if I would do aftermarket heads, but a forged rotating would be nice insurance compared to my current sbe

 

[Pro Stock John]

TFS 220s have a thicker deck, would be the main reason I'd do them, increasing clamping. Because I've seen some 220 vs 799/342 comparos and the 220s don't appear to make (a bunch) more power. I have heard really good results for gains from Brodix heads but they push the budget.

I might need to keep the 5.3 as a back up too lol.

 

[Boostie]

What do you anticipate the total cost of this build? Always was curious on having one done on your own verses buying one of the local engine "packages" with the parts of their choosing.

The internet has got me all scared with ls7 style stuff

Tie bar would be cool, even the morel drop ins are supposed to be really good.

 

[Pro Stock John]

boost21, I'm not sure yet. I don't know if it would have been cheaper to buy all the parts from an engine shop (I think though Summit is very competitve on prices so I think it's a no brainer), but honestly I like buying from Summit and one of the guys over there who is over the Pro LS line has been extremely helpful to select parts.

bob hope, yeah the internet says LS7s bad but again J Capiz never hurt one. I might change the lifters still debating it. I have LS7s in the SBE.

Plus, with Summit no d%%%ing around on whether something is in stock or not.

And im sure they will be good with returns if god forbid there was some sort of issue

 

[Pro Stock John]

So I'm going to try to order every part from Summit. I'll keep finalizing the parts list, including the actual Summit part numbers, and then do a total. I don't even know what the total will be.

I put the Johnson link bars in mine. Was told the LS7 lifters don’t really “fail”, but at high rpm then tend to compress slightly and basically are robbing yourself of power and consistency.

 

[Pro Stock John]

Hmmm I'll talk with my guys to see if they have had them bleed down like that.

 

[Pro Stock John]

I updated the first post, added some missing part numbers and changed a few.

 

[Pro Stock John]

Boxes are arriving.

 

[Pro Stock John]

I'm waiting on pistons, got a notice might be mid September.

 

[Mr_Roboto]

This is gonna be good.

What's it like to have that kind of money?

 

[Pro Stock John]

Weirdo.

 

[Huggerorange73]

Weirdo.

I just want you to be my sugar daddy

 

[Pro Stock John]

This a budget build son.

I'm sure it is, but when you're buying parts...and don't know the total cost....it kinda sounds like it's not
