WTH are you trying to accomplish? Why not just go with a cam that matched your application instead of the "biggest cam I can"?I want to run the biggest hyd flat tappet cam possible without changing the torque converter or gears. The stall on the tq converter is around 2500. I'd like to install a comp magnum 280H, but I think the 230 dur + the 110 LSA may be too choppy. I'm thinking it may behave better with a 112 LSA
(355, 10:1, Dart 200 heads, Streetmaster intake, Q-jet, Tri-y 1-5/8 headers w/2.5 pipes, 3.54 diff, 3500# truck)
Call up a cam company and tell them what you did and tell them you need a way to fix it while giving up as little power as possible. I'd call Isky or Howards or Jones- they're all good at unusual applications.I'm concerned the 10:1 & iron dart heads may cause pinging. I'm thinking 230 & 112 LSA may bleed down some compression
yep, not 10:1- about 9.6:1 assuming measured volumes are the same as advertised and you didn't take much of the deck.72 cc Iron eagle 200's, SRP flat-tops #138085 for 6" rods), Felpro 1094 shims
I have the exact same engine in my vette (355 10:1). The only difference is that I'm using Dart aluminum heads, XE268H cam & a 4 speed.
Will look into it. I'd like to stick with a single pattern cam if possible (single pattern has a more old school "rhythmic" sound unlike the dual pattern cams like my XE cam IMO) The streetmaster intake I have on my vette pulls harder than the Weiand 8004 I had on it, plus it has an oil fill tube which is a feature I need. Another intake option I may consider is an Edelbrock C-26 dual quad.Try this cam. Comp cams Dual energy 275DEH-10 it is a much better choice for your truck
and will not cause pinging problems. makes lot of truck torque and power and will work very well with your 2500 stall. You'll like this one.. Ditch the old school obsolete Streetmaster intake manifold.
A modern dual plane manifold will do everything better.
The cam is comp cams part # 12-209-2 275-279 219-229 @ .050" .462-.482 110 lsa
I've heard some strange things on this forum, but never the "like single patterns for the sound" line.I'd like to stick with a single pattern cam if possible (single pattern has a more old school "rhythmic" sound unlike the dual pattern cams like my XE cam IMO)
Cool - thanks for the tip on the old school intake & cam :thumbup:if you want the real sound of he 60's era you need a solid lifter cam in a wide 114LSA.
use Crane Cams cam #110941 It will have the right sound you want.
Get a dual plane off a old 327 and use a carter carb.
The edelbrock C3BX is right out of that era.
So is the Weiand 8016
The Street master is a 70's disco era intake manifold.
60's was solid lifter cams dual planes and dual quads.
You will need to recuve the distributor. bigger valve lash ='s more 60's era solid cam sound.
smaller valve lash ='s rougher idle.
do not go looser on the valve lash than +.006" looser
than the crane cam card spec. you can go up to .012" tighter on the lash.
the lash spec is .022" hot. so,,, you can vary that from .028" to .010" and get a different sound from the cam.
This will not harm the cam or your motor. but will adjust the idle sound to your liking.
adjust the valve lash once a year.
