30696bird

Need some help guys. I spun a few bearings in the 96 bird in november so I'm in the process of rebuilding it and figured while I have it apart I would make a few mods. Here there are........ Jet hot headers, cc306,home made ram air,! A.I.R.,!egr,hooker cat-back,pcmforless,taylor wires, ported heads,160 thermo,and all the free mods and a few I'm sure I'm forgetting. Anyways, the main question I have is, for the set-up I have the Machinist doing my heads said if I go with the 1.6 roller rockers I would have more lift but I would LOSE torque, is this true? And also, any advice on the reinstall would be appreciated(I will get engine back from machine shop in a week or two). Thank you.

Torque loss is possible, I guess, higher lift= more power higher up, possible power loss down low. I'd get them anyway.

But I would suggest some head porting and polishing for that 306 of yours- it would probably run a lot better with better flow #s.

Yea, all its doing is moving the Torque range around. You might gain a lil but your torque peak will be like 500 rpms higher err somthin...

Thanks for the replies........I don't know alot camming. BTW,The heads are being ported.

it will indeed mess with torque. like said before, just move it around, but I don't think the added lift is the whole cause of that. When you change the Rocker ratio it also effects the duration of the cam, not by much, but still a few degrees. that will effect the peak torque range, to be about 500 rpm higher, as said before. Good luck sounds like you'll have a good runnin car after all is said and done.
