Intakes under stock hoods?

What intakes would you guys recommend for a carbed L98 build under a stock hood. Would be looking to pull around 6000rpms give or take.

Re: Intakes under stock hoods?

TPIS Miniram or FIRST Fuel Injection set up will be your best bet to replace the TPI and fit under the hood.

for a CARB motor ,the edelbrock RPM air gap is hard to beat. IMHO

best carb intake but he'll need a drop base air cleaner or the carb top will hit the hood.

Re: Intakes under stock hoods?

Thanks guys yeah I already have the drop base air cleaner on my TBI now im just wondering what carbed intakes yal like that can pull 5800-6000 rms. I couldn't remember what I used last time on my 350 vortec build but I remember having to use a 2in filter also I think.

Re: Intakes under stock hoods?

Then the RPM Air gap is the intake you want. 1500-6000 RPM range and is dual plane so good street manners.

Re: Intakes under stock hoods?

If you're using vortec heads the GMPP Vortec Eliminator is a good intake, doesn't fit under a stock hood though....it's also a single plane

Im probably gona use iron L98 heads but if I go vortec again I think I had used a summit vortec intake last time that seemed to work well. Main thing is I will keep my stock hood but want to pull 5800-6000 rpm range.
