I placed the last order for shortblock parts today...I'll have everything I need for the short block by next weekend <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I have aquired a low mile (~20K miles) shortblock that had a melted ringland...machine shop said the bore was perfect so I'm using this as a base for the buildup <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

This is a LOW BUDGET shortblock...I could've spent tons of money on the bottom end but I wanted to see what I could do inexpensively.

3 things I didn't skimp on:
1) rod bolts
2) timing chain
3) oil pump

I'm replacing all 3 known LS1 problems with quality replacements. ARP Pro2000 rod bolts, Katech ported oil pump and SLP (*cough*Rollmaster*cough*) double timing chain with nitrated gears <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Other than that I bought a set of replacement GM pistons and rods from valvegod, Total Seal Piston rings from summit, Clevite 77 rod bearings from Summit, crane OEM replacement lifters from summit and Replacment main bearings from Katech. Due to the low mileage of the motor I'm not replacing cam bearings.

Top end of the motor will consist of GTP S2 5.3L heads milled .040-inches (2.02 intake) and a 232/232 .574/.574 112 camshaft <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

I'll build the bottom end next weekend and once the heads arrive (hopefully less than a month) I'll finish off the motor and install it <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Exhaust will also be updated to Dynatech stepped headers, 3" collectors, 3" bullet mufflers off the collectors, dual 3" cutouts then a 3" y-pipe back to the borla via a 3" flowmaster y-collector I bought.

Hopefully it'll haul A$$ <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Can't wait to see it in action. Why the small cam? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

CHRISPY

cool looks good!! I would have went a little bigger on the cam <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I take it will be mostly NA? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Do you think you'll have enough gear? hahaha!
Cheers,

I'm not lining up behind you in the staging lanes. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> The way you launch something has to give. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> I'm sure its going to fly. Good luck.

Congrats! Could you post close up pics of the chains & plate markings when you get them? I'd like to see exactly what they are using.

JPR

Thats really good news Bri! Let me know if you need a hand!

Sounds like a nice budget setup you have planned.

Tin Indian

Well, those $$$$ GTP stage 2 heads certainly arent "budget".

Sounds like a real nice engine when you are finished.

Good Luck'

Sounds like a good setup Brian! Good luck getting together.

Ron, the heads are where the power is. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I don't think Brian minds paying a few extra bucks for some extra hp/tq. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> I do agree that a good clean up w/ stock valves would be considered "budget" though.

Will this be the "biggest" hydraulic cam ever used in a street-driven 346ci LS1 motor?

FEAR THE LS1

FB, can you tell us what you dropped for $$ so far on just the parts you listed?

I'd just like to know for future reference when I do a rebuild.

Thanks!

PSJ had this same cam as well (this was the old GTP #4(?) cam).

well someone I know tried quite a bit bigger in a 346 but it didn't perform as well...but it did go low 11s <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

on a sidenote...my heads are DONE!!! woohoo...I gotta pull the heads off the car tonight to send Craig my double spring setup so he can do final assembly <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Fear...I'll look over all my receipts and get you a ballpark price maybe tomorrow

CHRISPY

I've heard of 242 duration cams in 346ci motors. As has been stated 224-230 seems to work best.

I ran the Lumberjack cam at one point in my 346ci motor:

236/240//111

And a early GTP cam:

232/232//116

Sounds like an awesome setup!! Good luck with it <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Try not to break anything... make sure people stand back a few hundred feet when you launch <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" />

well the short block is built <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

just waiting on heads...shipped Craig my double spring hardware via Priority US mail Friday and he hasn't received it as of yet

<img border="0" alt="[guns]" title="" src="graemlins/gr_guns.gif" /> US Postal service

so I dunno...if he don't get them by Friday..I guess I'll have to buy new ones to get the heads finished and the motor buttoned up <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

This sucks <img border="0" alt="[whiner]" title="" src="graemlins/gr_cry.gif" />

Oh..the block I took out was in SAD SAD shape haha <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
