1900 or 2300 Not sure what to get, leaning towards 2300 but sure it is the best one for my build. First this is not a drag car or daily driver. It is in a 71 camaro and only goes out on nice summer days. I do like long drives, did the hot rod power tour last year with it but most driving is weekends only.
LS2 5 thousands over 10 - 10.5:1
forged everywhere, arp bolts everwhere, coated everywhere
ported 243 heads 64.2 cc
cam 222/230 597/600 115las +2
7.425 pushrods
rear gear 3:55

There's little if anything that a 1900 will do better than a 2300. I think the price difference is about $600. If you ever decide to get rid of the 2300, it well sell quick and easy.....and you'll get your $600 back +.
A used 1900 might be a bargain though. I've seen them go for under $4K.

We used a 2300 on this build, and I wouldn't go with anything smaller.

Thanks, your compression ratio will be just fine. In reality we should of gone a little higher with the compression ratio as it would of been easier to make power. Bob

I have both and it depends on your power level......600+ rwhp I would choose 2300 and 8 rib otherwise 1900 and 6 rib 
don't buy MTI's bs I ran their 720 rwhp 1900 setup and got 652
2300 same pulleys 712
2300 at 650 had notably higher iat than 1900 at 650

Well here is the thing. My ECM is a MEFI 4B, anyone familiar with those. It is an open loop system using a speed density calibration or I can run it in closed loop using narrow or wideband O2 sensors. So no MAF or IAT sensors. Will I get a proper tune with this?

the 2300 had a higher IAT?

the longer you run in high boost, the higher the iat climbs-not linear but it does get hotter.
not sure how you could tune between a short run and a long run without iat spark table other than less timing than ideal. I expect to add meth pre rotors and intercooler and will see if that stabilizes iat.

yes the 2300 was hotter at the same power level - 'supersub' has a good fix
