Low Lash solid roller ls3 build
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 9” big ends narrowed 3” 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. Didn’t 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 wife’s 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 didn’t 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.
I’m 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 2” 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 10’s on Motor. Suspension is Viking on all fours, tubular lca’s, etc. I’ll 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 haven’t bought yet lol.
ARP Main studs.
Modified heater box. Only have defrost and legs.




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

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.
