[PONTIAC LARRY]

Digging up this old thread since my 2021 refresh started but sat bagged up to 2023 and just got back to finishing up a fresh engine combo . the old 455 still running in car but didn't race it for the last few seasons. Been running a variety of our vehicles , ran the 454 C10 in Super Muscle in 2020 2021 (8 sec 1/8) and won or placed a bunch of times and switched to Outlaw last year a mixed bag and could bring the slower cars or anything and bracket against anything even 6 sec electronic cars against my 7 8 9 10 sec whatever I bring. Did well and made semis and runner ups a few times tough class but also pissed off some fast cars putting them on the trailer with my 70 350 Olds Cutlass wagon .. So my started in 2021 new stroker that sat up last year is together its a 74 400 block +060 over with a Eagle forged 4340 4.25 crank I score a deal on that started this build. Butler-Ross flat tops and 6.8 4340 I beams with 7/16 ARP cap screws, balanced with new HD flex-plate and balancer etc. Had bought a bigger solid roller before this I have yet to use to get more in a actual race grind over my small street roller I have been running so new one is a Howards 261/269 @050 108 LSA .620 .620 vs the old Ultradyne/Bullitt 242/252 @050 112 .566 .566 on the old 10.9:1 #16 iron D port combo.. This time I am using my buddies KRE 310 D ports 85 cc but need to check actual CC he got them second hand, but should now be 93 octane friendly somewhere 10.5-11.0 after I figure that out. Block is decked a little and .005 in the hole , My unbranded polished Warrior intake I got a while back actually seems to match these 2.30" tall heads so I won't have to even do anything to it and have a 2" HVH Super Sucker tapered 4 hole on top with a classic 850 double pumper. Same 1.75" Hedman heads , same 10" converter that load flashes to 4000 should still work well. Same 3.64 gears MT SS 275 DR's looking forward to the spring races look to get it in and running in February .. If its only 50 HP stronger so be it but there is potential to be 100 HP more than other combo well see. I would love to be able to run 7.0 index stuff if possible, maybe the drum brakes get updated after that..
