Questions & Answers

I have a 1987 Chevy R10 350 SBC with a throttle body and it has an O2 sensor already in the exhaust, so I was wondering if this would bolt on my motor or is there any modifications I may need to do? Thank you for any help or advice.

Will this kit fit my 74 cougar?

Asked by: Guido
Thanks for reaching out to us. These kits require a few field modifications to bolt on but they are so worth it. Basically you will need to have a bung welded into the exhaust pipes to install an O2 sensor and upgrade your fuel pump to be able to develop the pressures required. Your vehicle should have a return line already plumbed to the fuel tank that you can utilize. Depending on your intake bolt pattern you might need a spacer / adapter for the base of the carb. Well worth the effort... Have a great day!

I have a weber downdraft 2 bbl carb on my '61 Volvo, will this sniper 2300 adapt to my manifold?

Asked by: Kerry
This would not be a direct fit without the use of an adapter.
