The 337 is a great intake so if you have a chance to grab one I'd do it as long as the price is fair. It would be a better match for TF270 heads. I made over 800 hp with a 337 intake on my 514 dyno engine. That engine had MW ported Indy EZ heads. The 337 intake worked a lot better than anyone expected. It is a low profile intake so it doesn't look like it can make 800 hp but it did.
