All went pretty smoothly, surprised how heavy the speed engine is
Plan is to refit an Ls based engine and 6 speed box
Did consider the 4.3 or 4.5 option for some time, but I prefer the v8 characteristics of the LS and v8, ( and if i am honest, i don't much like the speed 6 or other straight 6 soundtrack in general , guess I'm just a v8 chap). Now that has been decided, on with the build
With the engine out, the chassis is in really good condition, a small patch near the headers has lost it's powdercoat but apart from that its fine, I just need to repaint where needed, no plans to strip the chassis off this time (this year anyway)
Ive remade the heat shields as the originals were scruffy and will fit those later this week, also I think have sorted the wiring connections, it all works as anticipated though I'm not certain how the shift light Arrangement works. I think ( after some forum help) it works from outputs inside the dash ecu, but we will see. I can drive the dash light from the ecu but prefer to use the dash setup.
Plan to use the existing rad as I found the Ls runs cold in the griff, so unless I'm into lots of track time I believe the existing rads will be fine
Tested the fuel pump, which puts out sufficient flow and pressure, but I will use the corvette filter/regulator to ensure fuel pressure at rails is maintained.

Serious stuff started. GM loom, emerald ecu, cable tb, so lots of the GM stuff needs reworking as it is designed around fly by wire
Nice chap from associated cables sorted me out with original TVR bulkhead and loom connectors, so it will plug into original loom with little modding I hope

the t5 will be replaced with a tremec 5 or 6 speed. both are heavier, but the low rpm 6th is very comfortable on long runs, so IF (and it is a big if), it'll fit ok, i'd prefer a 6 speed.
I've fitted a 6 speed on the griff, and though the exhaust runs a little lower, its a compromise i'm happy with....the front and rear of the tam is way lower than the griff, and to date, ive not had issues with clearance on the exhaust
the ls clutch is heavier than speed 6, but i am considering a lighter ap alternative

looms about done, will wrap it once its running and i am sure no mods need to be made
taking some more measurements, there is no way i can see headers fitting without relocating the steering column to the "griff" position in the wheel well....pity i didn't measure that before i started with the new heat mat.....
not sure if i should leave the column fibreglass in situ or remove it fully and reshape the area...

Tuscan colum is lower
does it intefere more with the headers or less do you think?on the ls conversions ive seen, the column is relocated to give header clearance, but the ones ive seen are tuscans, not tams., and measuring mine, i can see the shaft UJ will be problematic and relocating is probably the best solution
Don thanks. Any info will help! I had heard that the proximity for the starter was a potential issue. I have a gm Ls starter heat shield somewhere I will have to dig out for a test fit
Spent the weekend messing with cam and springs for the tam engine. Won't bore you with specs but looking to get around 480 from the combination Also still keen to see if I can use the 6060 I have (same as griff) as the gear change is nice compared to Tko I've had before
