Re: Need Some Engine Advice - 383 Stroker
OK, here's my recipe. If you could change to a higher velocity (smaller port) head it'd be even better, but, assuming you keep that:
- Replace single plane Team G intake with Edelbrock Performer
- A cam with way less duration like 208 degrees at 0.050 max (factory 300hp cam is 190-something, after all)
- Large Dynomax mufflers (no drone, quiet at idle, loud under load) with pipes out to behind rear wheels at least, ideally past bumper
- Ideally, have carb dyno tuned by reputable old guy (not millennial tuner dude)
Everything else should just work. Basically you've got a motor there tuned for 6000rpm and by changing the cam and intake you "reprogram" it to run at lower RPM.
That combination would yield a torquey, quick responding truck that was made for in-town driving and the occasional blast from a stoplight. It'd be quiet unless you were trying to be loud. I think you'd enjoy it a lot more!
