Modified cams.

The stock cams are about very low end.
With a mild tuning profile you will hardly lose anything down there and get a good gain at midrange.
Use the longer opening mainly for overlap and let the intake close just a little later than stock.

@sonny You saw this before, so this is just here as a gentle reminder.

The camshafts Nev made for me, and helped me install (along with key assistance of @warp9.9 - and others on this site) added 18 hp, and raised the entire curve, to wit:

Installation of Neville Lush Racing "Street" cam shafts - coda

And following . . .

You may want to look there again.

And he says there is likely another 18 horses were I to spring for a 41mm header pipe going to a larger collector and tail pipe -- just not in the current budget.

If you do your own work -- and I know you do -- @Neville Lush street cams mod is the best value out there, after RAMAir, and a slightly less restrictive exhaust (e.g., clean cross-over and TORS or the like).

Was going to point to Neville's awesome drop in cams. All the plots I've seen of them show a healthy raise in torque everywhere and they carry power up top a bit better as well.

If unwilling to lose low end, they are the only option imho.

Thanks for the info. Missed the final outcome on your installation Joesmoe. Looks like a go on the cams.

Ditto on Nev cams. I dropped one in in 09. He's a great guy. Always ready to help.

Didn't mean to leave you out, @STRIPES
