Re: Edelbrock intake/Holley carb question
The folks at the store should know which one you need.
Why not use the factory unit bolted to the rear carb stud ?
Adjustment after the fact is another matter.
Don't touch the sheath release button, just reinstall the throttle valve assy as it is now..
Factory adj is to clip the unit together, then floor the throttle.
IF the trans shifts at this point, mark the sheath where it extends through the lock.
For a softer shift, move the sheath forwards giving slack in the cable.
For firmer shifts take slack out.
I bought a 88 Chevy 1500 in 89 for super cheap. In those days they would wear to the Hard Shift side of the adjustment. The shift would feel like it's gonna tear out the 3rd member.
A 2 minute adj and it was perfect.
I could get OD and lockup below 48mph, and 18+ mpg !
If you go too far either way the tranny will be stuck in 1st gear[700r4]
L460E's have no throttle valve cable.
On the silicone sealer, make sure it's "Oxygen Sensor Safe" I prefer Loctite Gold RTV.
Use more than the book says on either end of the intake manifold, I use about 3/16" bead as this makes a bulge on the inside and outside of the intake.
When putting a intake on my L-98 Vette motor, I used EXACTLY what the GM Service Manual said, something like 1.5-2mm
I inspected the rear of the intake with a mirror and found a gap where it did not contact!
Hence the increase RTV bead.
A larger bead will help keep it in place if you experience a backfire.
While I'm drivelling, a comment on the intake.
Is your Torker like the old ones, a 360 Degree ?
These work fine from 3500 rpm up.
If it's still new in the box, "consider" swapping it for a 180 degree intake with a torque curve from 1500-6000 rather than the Torkers 2500-7500.
I put a Torker on my Glastron Carlson 327 and it took forever to plane out then pulled fine from mid-range to 6000
