Hey all,
I'm been considering a performance upgrade for my Mustang engine for some time, and I'd love some advice and/or suggestions.
I've got a '67 Coupe with the matching numbers 289. About 6 years ago, the engine was thoroughly gone through and rebuilt with a higher performing cam, new pistons/rings, 3 way valve job & ported and polished heads, etc. Here's a post with more context for those interested. I also put on an aluminum exhaust manifold, headers, Holley 4 barrel carb, electronic ignition, and a few other things. The dyno run a few months ago shoed 234 RWHP and 289 torque at the wheels. Pretty respectable, but I'd like to add a little more power to further enjoy my car for my weekend cruising, weekend road trips, etc. I don't want to sacrifice any drivability for more power, but I'd like to maximize the power while maintaining superior drivability on the street. It's not a race car for me, but I want it to be more of a "canyon carver" to stick with my brother's LS3-powered '65 Impala.
I want to convert to EFI, and I really like the FiTech Go EFI Power Adder. I also would like to supercharge it, and I like TorqStorm's kit for SBFs.
1. If I do the EFI and Supercharger, and I leaving a lot of accessible power "on the table" by not upgrading to aluminum heads that can breathe better than my reworked stock ones?
2. I forget the specs of the cam, the pistons, and anything else that my engine builder may or may not have done during the 2012 rebuild. Can I bold on the supercharger + EFI without worry of blowing something up, or do I need to consider a different cam/pistons/top end that are friendlier to a boosted setup?
I'd love to hear your insights/suggestions. Thanks!
