Default Low Lash solid roller ls3 build

Welp since Iím coming up on the end the of my build, I figured Iíd post it on here. Now Iíve never done one these before so bear with me haha. First picture is what the car looked like when I first got it.

So about a year ago I picked up my 2000 1SC SS, drove it for a few months and tore it apart. The car will remain a 6 speed car. The trans will be a T56 from RPM with a monster clutch, Quick Time bellhousing. 8.8 rear with 9Ē big ends narrowed 3Ē per side done by a buddy with a 4.56 gear , spool, 35 spline axles.

Was going to build the ls1 that was in it but ended up having an aluminum 5.3. Didnít know this until I started taking it apart. So traded the shortblock for an ls1 shortblock had a set of diamond pistons and lunati signature series rods for it already so took it to the machine shop and had him throw it together. The plan was to do a 12:1 ls1 setup with a LLSR. Well long story short, a buddy needed a new shortblock so I gave him mine and he bought me an ls3 shortblock. Ended up picking it up for $500. Took it to the shop had it checked and all was good. Tossed around the idea of just keeping it a nice 93 pump setup but after talking with my wifeís uncle(my machinist) I decided to go with a set of 12cc Mahle pistons for a 13:1 setup on e85, a set of eagle I-beam rods, and a stock crank. He was very pleased with how it all turned out. So I get a hold of Steven at Cam Motion to spec my cam and tell him my goals. He sends me the specs(245/257 .696/.680 111lsa) for a low lash solid roller and tells me with the right set of heads(mast or Frankenstien) and a Holley hi-ram or equal intake my goal should be attainable. The reason for a LLSR was because of the valvetrain stability and I didnít mind turning the car higher in the RPM. The car will still be driven on the street as my definition of a street car and others may be different.

Iím still deciding between which heads I want to run though. Most likely the Mast medium bore 255 heads. Going to be running an LOD speedworks intake with this setup. Jesel rockers will also be ran. The setup will also have 2Ē TSP headers, phab x-pipe dumped at the rear axle, pro stock1313, ATI balancer, electric water pump, crank scraper, oil pan baffle from improved racing. The car has been put on a diet also. The goal for the car is to run mid to bottom 10ís on Motor. Suspension is Viking on all fours, tubular lcaís, etc. Iíll post what pictures I can and grab more later on. Also any input on which heads one would choose over the other is welcome also. Both have great product which is the reason I still havenít bought yet lol.





ARP Main studs.





Modified heater box. Only have defrost and legs.

Awesome build/plan!
I would and did run MamoMotorSports (MMS) LS3 Heads, with my LLSR Build.
AFR Castings would be my choice.
( The AFR LS3 Heads were not out when I did mine, I used the TFS Version)
I think you will have enough Power to go 9s.
Following.
Good Luck

thanks man! I have considered the AFR mongoose castings also. I just wasnít too sure if they were any better than the other two I had listed. If the car goes a bottom 10 or high 9 Iíll be happy for sure.

Well, I’ve decided on heads and will be going with a set of factory castings done by Frankenstein. I’ll be going with their stage 2 CNC program after talking with them about my setup. If they still had the 10* 255 head I would’ve gone that route, but they no longer have them.

Hmmmm. Now what's going to feeding the heads with the 245/257.696.680 111lsa cam. Chris does have a cnc program for intakes and you get a discount with ported heads? Holley hi ram. Ask them about it...


Just riding and seen a engine shop. Just left cutting auntie's yard or block.
Met with engine builder Zach Nelson owner of tafindustries. Winner of the EMC with the NOS Ls 366 with the CID intake from SAM().. Funny thing is he's in my old neighborhood, 8mins away from my house now. We came to agreement on everthing for b&b (blueprinted & balancing). Also he would like a house near the shop. Hmmmm, just so happen friends build new homes /rentals and he asked about the new homes behind the shop (aunt's house is behind the shop). Funny thing is we built those 3 stories homes and building a 5000+sq/ft home right in the hood. everthings right how i would like with everything no more than 15min away for everthing, tune included @ fastlane. Call it being patient.

I’m going to be running an L.O.D Speedworks intake. From the info I’ve found, it looks like it’ll perform close to the same as a high ram. My original plan was to run a hi-ram or something similar and the speedworks intake seemed like the closest comparison

If you had good clearance, i'd say CID intake. Got a lesson from Zach yesterday.

I’ve got clearance for one, I just prefer to use either the hi-ram or this LOD Intake.

I know you have one.
You need another one so you have a DOHC pushrod engine.
Get with the times.

Who did you talk to at Frankenstein? I'd call and ask for J.R. and have him talk to you about the F310 10* LS3 castings they are pumping out! LS3 casting with raised runner ( cast to fit any intake) and the exhaust ports are centered to the valves vs off set. I'm getting ready to build the 1st engine which is a 416ci 13.8:1CR with their F310s but with a CNC ported high ram through them as well. They are knocking the CNC intakes for $400.00 which is a killer deal.

If you get over 850 @ the crank maybe they sound good with a 416 but not really.

418 with factory FED ls3 heads made 811 with 13.2 compression
Cost vs Hp?

Yeah their stage 2 program ($1749.95) did well for me on a SBE setup. I'll see what I can do with my 416 and their F310s and have something to show some results on.
