a $6000 ls1 with $500 in it WILL WALK your lt1 badWith the money you save from buying an LT1,
buy long tube headers and a CAI and you should be running right next to ls1 just like myself. You'll need a high stall converter if its an auto to get you in your power band though. If its a six speed just buy some street slicks and launch at 3000 rpm. Not much is needed to keep up with LS1, about $1000 in parts.
My favorite place to look for cars is craigslist. Say you buy <100,000 mile lt1 for $3000-$5000 plus $1000 mods your at $6000. You could find a lS1 for say at about $8000 these days so you will be saving about $2000-$3000 if you go the lt1 route.
And the opti spark aint no big deal, just go with the OEM though cause ive seen dyno graphs of aftermarket compared to OEM and they are the same.
Just replace the waterpump when you do the opti so you wont have to do it twice cause if the waterpump leaks on the opti....poof there goes your opti again.
Optis are good to last 100,000 miles if no leaks from the waterpump are present.
People only replace one or the other and then they got to do one job twice.
OEM opti are about $300 and water pump is around $100 i believe. But at least you will have peace of mind you have a new water pump, thermostat, and opti.
Of course maintance on any lt1 or LS1 is required with around 100,000 miles
