Just asking for opinions and seeing if the L98 305 is worth modifying.

A friend has an 88 GTA, and is willing to put money into this motor. Only thing is that it seems to be delusional about the power level he possesses now, and the power level he may end up with.

He thinks he's making at least 251 HP with a Hypertech chip, Flowmaster catback, TPIS airfoil, and a K&N air filter. I'm not too sure about that.

Anyway, what's a decent end power level he can end up with if he adds heads, cam, and new intake??

Thanks for your answers guys.

 

Well, my friend just built up his 305 TPI w/ the following: aftermarket cam(dont know the specs. forgot to ask), some slight portwork of the stock heads, headers, siamesed runners intake manifold, cold air intake, no cats., and a flowmaster catback. He is guessing he is somewhere around high 200 or 300 hp at the wheels. He just ran low 13s on DRs and a non-posi rearend. So I would say the 305 has potential, it just depends on what your friends goals are for the car.

 

The L98 is an 350 and the LB9 is a 305

 

I was going to ask what a L98 305 is?

 

My thoughts exactly

 

Adding an aftermarket intake (such as a Holley Stealth Ram), some GOOD heads, and a cam would make that 305 bump like a ****

 

31 HP to the crank with the flowmaster catback being the only real power adder? Probably not. If he is happy with the engine though, then why not build it? I would not recommend breaking into the heads however. Once you reach this point it probably is cheaper to upgrade to a 350. I would say to for now get a modest set of headers, possibly an HSR, or just spray it.

 

You know, I thought it was weird that he said it was an L98 305. He has some information book that says there was an L98 305 too, but I thought it was wrong.

Anyway, yeah he seems to want to have one of the baddest 3rd gens with a 305. I'll just support him then, and come here when it comes to some good advise on modifications on his car.

Thanks guys. Carlos

 

L98 is GM's ID for a 350 TPI only. So he is mis- identifing a 305. Because no such engine exist as a 305 L98.

 

Sorry, that role is already taken

 

Well then maybe you can help us out....and then we can overtake you

 

Help you out sure, but overtake me you shall not

 

high 200 RWHP or 300RWHP. that must be a HUGE cam and head work....if thats the case why the hell did i buy an LS1? i have trouble believing it runs low 13s but thats just me. and why even waste the money on DR when you have an open rear?

 

Good question
