L98 intake question
Hi guys,
Ill be brief... My step son aquired a '91 L98 TPI and is in the process of rebuilding it from the ground up. I apologize for the vague question but he doesnt know which intake is best.
He is looking to do a mild cam, and do away with the fuel injection. This motor will not be in a Vette.
I just know you guys would have the answers, or point us in the right direction.
Thank you in advance,
Don

What does "(Vortec)" mean? The Promaxx 2171 head doesn't mention anything about being a "vortec" head.
I think most would likely recommend an Edelbrock Performer RPM Air Gap intake. That thing is a winner. I think it's a good match for your cam/RPM range and 185 head. Not sure he's going to get 400 NET hp out of a 350 with those parts, but it'll be a fun car, for sure.
