Hello,
I have a '77 Bandit Trans Am with the Olds 403, and this winter I will be working a bit on the motor.
I've bought some #5 heads (off a 350 Olds) along with an Offenhauser inlet manifold.
What cam would you recommend and what other modifications should I considder? I'm looking to get streetable car but with a bit more punch! Let's say in the region of 400HP. This should be possible, yes?
I'm wondering as well if an injection system is worth the effort (more so for better running at low speeds around town)?
Looking forward to your replies.
Regards,
Rafe

Sorry no direct help (I'm a BB man myself), but you may want to try Here (http://www.realoldspower.com/phpBB2/). I would read the "Engine Builds\Combos" section first then ask your question there. I know that there are several T/A owners that frequent the board and can help with header selection and such too.
