I ran the TR 230/224 for quite some time in a previous F-Body. It had the same street manners as the TR 224/224, but it made lots more power up high. Same driveability, more power, it's the reason the reverse split cams came on to the scene in the first place.

236/230 here. street manners really arent too bad. the car put down 390 rwh 375tq, when it was cam only. since then ive added heads, a pulley and a water pump, and will be going to the dyno tomorrow to have #s from that. it makes great power up top, and fairly decent mid-range. up above 4500 you can really feel the car pull. i went 12.5 last fall(cam only) with a 1.9 60ft. the stock gears are killing me right now, hence the reason it states on their website to use this cam with 4:11's or higher. ill have the 12-bolt in in a few weeks, so it should be a mid 11 second car after that.

the TR227 is what i was looking at i have a set of ported heads coming in (215 cc intake and 80cc exhaust) and ls6 intake mainfold with QTP headers. i got chromoly pushrods and yellterra 1.7 rokers arms to go with the new cam so when it all gets installed i will let you know what kind of numbers its laying down.

I just saw a guy dyno with a TR236/230 today, and he put down about 394 rwhp. He had heads and headers with it also. He said he gets a lot of surging and bucking at around 1500 rpm, but he likes the cam. My cam acts the same way, but I made 35 more hp than he did.
got my car dynoed after the head swap today. the tr236 put down 390/375 thru true duals(cam only). there is now a magnaflow catback on there, and the car put down 425/410, so im very happy with the #s. now i just need the track to open up, and i can have some times to go along with those numbers
hey i got a comp 228/224 with .588 .567 112 lsa, that i am gettin ready to install. how would this react to a big shot of spray i have heard from some ppl that it would blow the nitrous out the exhaust, and that i needed and exhaust bias cam. does anyone have any info on this please?

236 here, M6 car has all bolt ons with stock 98 heads put down 410 to the rollers. I have 4.10 gears and you really need to keep this cam over 2000 rpms to not get the bucking other than that it is a very drivable deal.
Oh yeah, it lopes like mad, with the cut out open people come up all the time wanting to know what i have.

Something is wrong with that guys combination. We just did a '98 model Firebird with a very crappy y-pipe and a completely stock TB, LS6 Intake, and NO dyno tricks that just did 410 RWHP with the original '98 heads. Unless the guy has an automatic with a loose converter those numbers are low for that combination.
Hey Geoff. My car is untuned. I'll have some new numbers in the fall when I get the tuning sorted out! I have no doubt that 420 is obtainable with a tune! So technicly there is something wrong with my setup! It's only half done! LOL!!
