A feeler thread for a potential mod(ification)

Cool project, sounds like you've built a sweet motor. I feel like this could use a tl;dr... Is this the configuration of the engine?

B230F block / crank
GM Vortec 4.8/5.3 Pistons
158mm rods
RBP intake
RBP ported 530 head with 58cc chamber
RBP downpipe
V Cam
10.4:1 compression

I have 2 amendments to make up that list:
1. I accidentally wrote 58cc chamber, it's actually 57cc or so.
2. 0.027" MLS head gasket.

The only added notes that I have is that the downpipe is just a modified Volvo stock downpipe, with the area right before the merge cut off and replaced with a slightly squished 2.25" pipe, and that the rods have to be crank steered with room for a 24mm wrist pin in the bushing. If you want to copy it I've got 36 rods with the correct provisions.

Update on the situation;
1. Still no dyno stuff. Sorry. Next time I swear.
2. Make sure that your heater hose clamps are tight so that they don't blow off your head and lose all your coolant on the highway.
3. Me and RedblockPowered spent a good 3 and a half hours doing runs back and forth on a highway, doing pulls, lugging the engine, and we developed a tune for the B230FLS blueprint. I suppose it's more appropriate to call it a tune for ultra-high squish engines, since that's the important part, and the lighter pistons simply make it much safer to do.



With 87 octane it knocks with a standard stock ignition map, however the knock is so quiet that we couldn't hear it unless we seriously cranked up the advance. Decreasing timing from stock results in no decrease in power, and filling with 93 octane allows a 20% increase in timing advance for maybe a 2-3% improvement in power. In my opinion that's not worth the additional cost for octane, so I stuck with the 87 octane map. I believe that it shows the efficacy of the fast burn characteristics, that so much change in timing can be made for very little gain.
