Had it towed to my tuner two weeks ago. Hit the jets today
Mods are in signature, but in case anyone wants more deets
Bolt ons:
Pacesetter long tubes
SLP dual filter CAI with descreened MAF
Hooker Blackheart 2.5" true dual exhaust
3200SS Yank torque converter
Torqhead 24XLink (LS coils and PCM)
Engine
1.52 NSA Comp Roller rockers
Tick "Hatermaker stage 1" cam (227/233 | .551”/.560” | LSA110+2)
Morel 5315 lifters
Lunati 73925K5 spring kit with Tool Steel Retainers
Heads had a three angle valve job performed by a local machine shop
Trickflow TFS-89036 (36 lb/hr injectors)

Most of this was performed earlier than I expected after I had a head gasket fail last Summer.
Used this as my opportunity to freshen everything up.
All new gaskets, new oil pan, timing set and pushrods.
343 horsepower to the wheels which I think is around 405-415 crank.
I dyno'd 282 RWHP on the same dyno with bolt ons and the torqhead conversion two years ago.
I'll go ahead and say it. For that kind of result, you'd have been further ahead to do a LS swap with a mild cam. I have a similar duration cam and did 408 rwhp on my LS1.

You don't do a build because it makes sense.
Unless you ran it on the exact same dyno as me, I don't think the results should be compared.
The LT1 has always been my favourite sounding GM V8. So even if I did an LS swap, it wouldn't accomplish my goal.

Track times and race weight? It's ridiculous to compare cam profiles between the two platforms and dyno sheets.

Auto or manual?
Nice results. 360whp is more than enough for a fun street car and in relatively light weight of an fbody will move. Gotta love that LT1 insta-torque and sound

Mine is a M6. I agree, the LT1 sounds better than the LS1.
Of all the exhaust setups I listened to, mod for mod, LT1s sound meaner than LS1s.
And the Hooker blackheart true dual system is the best sounding off the shelf true dual system. It only made sense to me that my setup would have both.
This is a forever car for me. I have owned it since 09.

My tuner said that the 365 doesn't count because it's when the converter "spikes".
So it's more like 343. I'm thinking it'll be drastically faster than it used to be when I finally go to pick the car up.
343 RWHP would put it above the common off the shelf cams by about 10-15ish horsepower
Is 40 wheel on the high side for just a cam? 40-50 wheel seems to be the norm for a cam only LS1. My car makes 290-300 wheel, stock internally. I would be disappointed if a cam and headers didn't add 40 or so to it.

Yes and agreed. Most cam only stuff I remember was in the 320ish range, however your heads are not 100% stock, either, so...............
Would love to see some track times with your new setup.

275 was bolt ons with stock torqhead tune
282 was bolt ons stock tuned
So add 45 for the cam, 15 for the valve job maybe?
Nearest drag strip is 3 hours away. The perils of living in rural Nova Scotia.
Most 3 angle valve jobs give around 20. Which just goes to show what a full port and polish will do. 40 whp from a cam swap on an LT1 is pretty decent. Shitty Hot Cams before a tune give around 35whp in an Fbod.
Either way you slice it, with a badass launch in decent air you should be low 12s, trapping 112ish. Not bad for a washed up 90s platform that won't ever break a sweat.

This car is setup for handling. It's got most of the Sam Strano specialty parts (koni yellows, strano springs, strano sway bars, etc) but I do think it'd do well.
Nearest strip is 3 hours away, I'd hate to blow my ten bolt apart so far away from home.
