For the little that you have done to that engine the factory TQ intake or the Performer will be fine.



He has aftermarket heads, IMO that fact alone warrants an aftermarket intake. The regular performer IMO is only good for very mild applications with stock unported heads. The LD340 would be a good choice for a combo with stock heads with a little porting. With aftermarket heads I'd be looking for something a step above. Performer rpm with an adapter and the transition smoothed out would be decent, if you have the hood clearance for everything. A used holley street dominator for small block if you can find one would be a decent choice too.
