EricJB Posted March 27, 2014 Report Share Posted March 27, 2014 Leave the ports alone. If anything match port the manifolds. Quote Link to comment
Z-train Posted March 27, 2014 Report Share Posted March 27, 2014 As Mike mentioned earlier. Reverse for larger ports and carbs. You will 'bog' out in the lower RPMs but get you power up high. That is why all the race guys have larger ports and carbs, they are mostly staying in the higher RPM range, not so fun for a daily This would be correct. Quote Link to comment
Doctoraudio Posted March 28, 2014 Author Report Share Posted March 28, 2014 Okay, I found a few double set of parts.One of the things I like to do when I am building stuff.Is to find the lightest and the strongest parts.I have a timing chain spocket that weighs 600 grams. And another that prances in at 510 grams.That seems to be more than a different batch or lot.They look a little different!One the numbers are stamped and easy to see the other is stamped but much small.you can barely see the numbers on the second one on the right Quote Link to comment

hang_510 Posted March 29, 2014 Report Share Posted March 29, 2014 duh, you gotta use the 510g. hainz should be able to confirm, but the heavier looks like an aftermarket piece Quote Link to comment
Z-train Posted March 29, 2014 Report Share Posted March 29, 2014 nope not joking! I meant joking as in where you think it matters. Quote Link to comment
datzenmike Posted March 29, 2014 Report Share Posted March 29, 2014 That sprocket is used on all 4 and 6 cylinder L series motors... all years. From '68 through the '88.5 in the Pathfinder. It's even used on the LD28 diesel motors. Quote Link to comment
john510 Posted March 29, 2014 Report Share Posted March 29, 2014 The heavier sprocket looks new,the lighter one looks very worn out.You would never know which was which horsepower wise.Put the newer looking sprocket on.Its probably a better quality sprocket. Quote Link to comment
datzenmike Posted March 29, 2014 Report Share Posted March 29, 2014 Both look factory but if one isn't, go with the factory made in Japan sprocket. Lightness is not the deciding factor. Quote Link to comment
Sealik Posted March 30, 2014 Report Share Posted March 30, 2014 The one on the right is aftermarket...looks a little rough around some edges If concerned...install one at a time and check (if any) chain slack. Quote Link to comment
dr.feltersnatch Posted March 30, 2014 Report Share Posted March 30, 2014 Agreed↑ one on left looks better quality Quote Link to comment
Kirden Posted March 31, 2014 Report Share Posted March 31, 2014 Get a custom lite weight forged one made, because racecar... Quote Link to comment
datzenmike Posted March 31, 2014 Report Share Posted March 31, 2014 Weight not a factor. Quote Link to comment
Doctoraudio Posted March 31, 2014 Author Report Share Posted March 31, 2014 The one on the left does look better.I am going to try and get the head ready for the shop before the weekend.Once head is done, I can start putting it together after we finish putting all the holes in it.
