Thinking about Moving to an LS1 in the Formula...(Merv Please Read)
Chris can not get the block out, he returned the car, stock bottom end and lt4 heads and everything he had which was basically everything thats stock and gave me a few options.
He would pay me 1000.00 (I gave him 820.00 to start this and owed him another 200 or so upon delivery) and i could start over.... or he would keep trying to get the bottom end, finish cleaning up my heads and install the new valve springs, put them on and put it back in.
Now I would love to have my LT355 up and going. I was REALLY looking forward to my build. (I can detail the specs if wanted)
But in light of this I started thinking... I don't know how long this could take and I was supposed to have this car back 45 day ago. I could sell all my remaining items (LT4 Ported Heads (Less then 2300 miles), T56 (98k), MSD Opti (Brand New Straight from MSD), LT1 Vette Fuel Rail Covers, LT1 Pacesetter long tubes (Less then 900 Miles), LT4 Intake Manifold, BBK 52MM TB that was ported to idle correctly, T-Tops (I have a hard top not going to convert), LT4 Knock Sensor, LT1 Block (Probably for like 100 had less then 2300 miles but the rings were washed out not bored over) and my LS1 Complete Brake Conversion) and have a nice chunk of change.
My LS1 w/ Brand new clutch and flywheel (Upgraded from stock have to check again what they are) and T56 Tranny would be 1200 with everything I need. (I also have a spare 98 ECU, Coil packs and an LS1 Drive Shaft I can sell too I just remembered).
So with everything I make from selling what I have plus the 1000 from Chris I would have enough to make a decent LS1. I have some headers locally, I can make my current exhaust match up to them I am sure. (If not he has the Y-Pipe too)
I think I could put on an LS6 Intake Manifold, Bigger TB, LS6 Heads and Better Springs, Mildly Big Cam and some better push rods then tune her and be well within the money I would have to play with. I might even get to pick up a few extra's here and there.
But honestly I am not sure I could expect well over 400 at the wheels which is probably where I was at with my 355 anyway... but this will also not be a fresh motor like the 355 would have been... it has 80k on it.
I have no idea what to think... both options seem reasonable but one could take a long time and one seems to be more popular... I refuse to get rid of my current body I like my Formula. I just need to know whats going on and well... thats not happening so I have to make a choice. I either try to build my 355 else where for 1000 or I go the LS1 route and cash in on some of my hording and parts I have and a really good deal on an lS1 and T56 Complete.
What do you guys think?
Merv how hard is this, I have been meaning to PM you but maybe this is easier. I know you converted what all should I pick up? I was thinking about grabbing an LS1 rear end too but I get the whole front K-Member with the motor, everything to just swap over.
This is whats going through my mind right now...

I say keep the LT1 and let someone finish it for you. You already have the parts and tuning, so don't be lazy and look for the easy way out, and just get it finished.
At this point I have no idea when I would even get my bottom end.

I will look into it though but I really do not want something long and drawn out. Let me see what happens today.
I just wouldn't give up on what's allegedly been done already.

Good Luck!
