Hello all,

I've got an 88 Firebird base that is VIN 305 engine w/T-5 Tranny. In this car's history, someone dropped the L98 350 TPI in with the T-5.

What I am experiencing is super long cranks before engine catches, if battery is not at 100% voltage it won't crank. (will crank everytime when jumped, or fresh recharged, or when left on float charger)

I went to autozone and bought a 350 starter (they said it was compatible), but the nose-cone geometry does not allow it to fit into the bell-housing. (found that out after 2 hours under the car in the Lowe's parking lot ). So I have some questions for you:

Other than dimensional size, is there any difference in performance of a stock 305 starter to a 350 starter?

If there is, do any of you have any recommendations of a starter with 350 performance specs but 305 geometry?

Is there a bell housing for the T-5 that has the geometry to fit the larger 350 Starter?

Any information would be greatly appreciated!

Thanks guys

 

Some 350 starters will not fit the T5, but you know this now.

Recommend replacing the factory original style starter with one for a 93-97 LT1. It's a better, light weight design and will fit. It's a PMGR (permanent magnet gear reduction) starter as opposed to the original direct drive. World of difference.
