What type of power should I expect?

[Seven]

Curious what I should see (ball-park, doesn't need to be so specific anyone gets into arguments) from the following modifications (or a '19 GT350R)...

• Upgraded air filter
• Ported stock TB
• Ported stock IM
• 1 7/8 catless headers
• L&M Camshafts
• thinner HGs ( .036)
• Tune for E85

Happy hear either an overall whp ballpark, or just a net gain estimate

I’d guess somewhere around 490-495whp. Wild card is the ported IM I think. Not many have done that from what I’ve seen

I think that'd be fine. I'd ideally like 525-550whp (not from those mods, just in general), but that's close enough. I know I could get there on E85, but alas, it's not local.

I'd ask what aftermarket camshafts make (and maybe thinner HGs), but it seems like no one has done them.

Decided to bring E85 to me. Updated the build in the original post, I think I'll run it on E85 only and am curious what people think the mods I listed might do.

Would consider the CJ intake/tb but I keep hearing I might need to "lower the engine" and I don't know specifically how it's done and I'm concerned about what issues it might cause. If it's just something like "the oil pan is closer to the ground" - no biggie. If it's something else, well I'd have to think about it.
