The Air-Gap intakes are great intakes. The dual plane plenum provides plenty of low end torque where you need it and the higher rise with the air flow design underneath the plenum makes great higher rpm power for top end performance. The Performer RPM I had on my stock 350 worked really well. I couldn't tell any difference after I swapped to a Performer EPS, which is also a great intake for stock or mild small blocks. The 750 will be too big. Jetting only plays a small role in tuning a Holley. A 570 Street Avenger Holley works well on stock 350's. Do you have the stock cam in your engine?
