TBF the best throttle ever would be a linear plunger and a small blade in the centre for low speed and idle, take off then lift a conical plunger as percentages of W.O.T it's a restricltless throttle and as long as it's state is naturally shut then there's the fail safe for being stuck open so regardless of intake it will not have a restriction unless it's the ports manifolds of valve area
I bet it will run on the stock ecu, but it will idle bad and it will be lean af on tip in due to the huge increase in throttle blade area. Good idea to save for the aftermarket ecu. I think its a must to make this work since the early lt1 ecu is not very tunable. I am 5.3 swapping my c4, also in wi. Good luck!
What ECU are you planning to run? Even tuning an ls1 PCM to run an ITB setup to run correctly was difficult. The MAP and the IAC circuits were the most problematic. What are you planning for crank and cam position and ignition setup?
@PetesGarageandperformance lol currently trying to run it on the stock ecu with a tuneable chip. I do not image it will work, but I atleast have to try
i did what you said in the past slot drill intake with angeled washer with allen head bolt. I regretted it. Better weld and drill and tap the cylinder head for multiple reasons.
@@trollpatrolracing1535 I did it on a 350TPI, and retrofitted an lt1 intake with a remote thermostat housing. and drilled intake and plumb the water pass externally. The port alignement and vaccum issue, bad brake, bad idle etc. My 1996 LT1 had the kit you are refering to, GMPP optispark pate. I needed to do a key in damper pulley for timming, used a rear mount distributor. I have plently of friend who swapped SBC singleplane on lt1 they all fitted terribely wrong. Get your lt1 holes welded and drill sbc std bolt patern. Or you can order LT1 aftermarket cylinder heads with 350 sbc bolt patern.

The power of standalone ecus compels you..

You're right, the stock ECU will be a challenge, but it's a fun experiment.

You could use a rubber frost plug to plug your distributor hole……
@@toddgirard391 they actually make block off plate kits that include one for the distributor and coolant neck, so just ordered one of those

@@mathieusynnott8915 what were those reasons?
