Need a little help. I am going to swap the 305 TPI in my 1991 z28 convertible for a 350. Scoggins Dickens is selling a new vortec 350 for $2,109.00 (shipping included) with a TPI base intake for another $348.00. TRi-Star engines is selling a re-manufactured OEM 350 for $2,250.00 (this included shipping and core charge). What engine do you guys recommend? I will not be racing the car but do want a little get up and go.

The new Vortec fron SDPC.Why buy a reman when you can get brand new for less.The new motor should also come w/ a 100,000mile/5 yr warranty,IIRC. Is the TriStar an L31/Vortec,or,just a reman 350?

Because the vortec 350 is not a factory replacement to my 305, Scoggins is only offering a 1 year/12k miles warranty. Tri-Star's engine is a remanufactured TPI 350. Will a vortec, being that is a truck-based engine, have good performance compared to a car-based 350? Also, other than the TPI base plate, a 350 prom, knock sensor and larger injectors, will the vortec engine work in my car?

Yes the Vortec will work.I'm not real familiar with the TPI 350 & it's rating,but,a stock L31/Vortec will easily make 300 HP with 750 cfm of fuel/air & headers.Tuning will be necessary as will configuring an EGR,if you have to comply with emissions.

I have one from summit, no good from the get go. did not break in correctly, about 30,000 miles now, needs a rebuild, uses oil like a sonofabitch. but runs o.k.
