Gromm Racing

Some dyno results on the 5.7 HCI swap for @richez_101 . The base pulls produced around 325rwhp and fell off around 5,800rpm with a Diablo tuner. After a set of our ported heads, @compcamsofficial camshaft and ported intake, the car made 418rwhp @ 6700rpm and was still climbing. That’s just about a 100hp increase, 1000 rpm gain and a nice flat torque curve out of the 5.7L after @doc_350 put his tune in it. #grommracing #merica #dowork

Action packed weekend ahead of us. First we’ll dyno this 502 BBC for @ffrfabrication with a @vortechsuperchargers feeding it some air. Then we have three back to back LS builds going on the lie detector which include a 408 stroker, 416 stroker and a @dartmachinery LS Next based 427. We will be posting the results and videos with each session including a break down of components used. #grommracing #merica #dowork

@dartmachinery LS Next based 427 ready to head to the dyno. @scatcrankshafts forged crank and rods, @jepistons custom slugs, morel lifters, @che.precision trunions , ACL rod and main bearings, @arpbolts hardware throughout, @msdperformancee intake, factory LS dry sump system with blueprinted oil pump with increased pressure, billet timing set with IWIS chain, and @injectordynamics 1000’s. #grommracing #merica #dowork

Before and after port work on the Brodix heads for the 582. #grommracing #merica #dowork

Callies crank fitted into the Dart Big M and spinning like butter.

582 coming together for our customer Alex.

@g8mobbin408 didn’t waste anytime getting his @gromm.racing engine installed and fired up over the weekend. #grommracing #mericaagain #dowork

Set of oval port BBC heads we did for our friend @mansoor_almarri in Qatar. The heads were ported, resurfaced , bronze guides installed, hardened valve seats, competition valve job, stainless steel intake and exhaust valves, and fitted with a set of beehive springs and retainers from @compcamsofficial #grommracing #merica #dowork

OEM guides compared to the aftermarket guides that we use.#grommracing #merica #dowork

Can anyone guess what this BBC block is made from? It’s not aluminum and it’s highly flammable. #grommracing #merica #dowork

Another batch of custom grinds from the good folks @compcamsofficial just arrived. #grommracing #merica #dowork

Custom slugs for our 598ci procharger big block Chevy. These flat tops will yield a 10.5:1 compression and with their top ring land placed down .3750 it’ll allow us to throw some serious boost at them. The goal is 1000 reliable HP and with this combo that should easily be achieved. #grommracing #merica #dowork

Nissan VG30DETT. 11:1 compression custom slugs from @jepistons , @scatcrankshafts H beam rods, @kingbearings , @arpbolts rod bolts, main studs and head studs. @tomei_84 MLS head gaskets, and a bunch of other goodies from @z1motorsports . #grommracing #merica #dowork
