Matt,
Thanks you very much for all of that information. I now see why I am having a problem, and having to pull so much HP. I wrote this code over 11 years ago while trying to help someone out, and it only uses a single timer. Stan

Matt, 1st off THANK YOU for making a swing with cam selection! Ya Gota make moves to move forward. That you did, that’s what moves the Pontiac community forward.
2cnd I have checked out you and your dads beautiful cars on numerous occasions,they are breath taking. You guys are always in the motorhome so I really haven’t talked to y’all much My 2cents on your original question, have you tried merge collectors? I’ve always heard keep making the choke point smaller and smaller until it falls off then go back to the merge collector that made the most power. I’m in that horsepower range but our motors are way different considering I run a 18 degree big chief head. But for what it’s worth I have a 2 3/8 primary tube and a 5” merge collector that chokes down to 4”.

I was concerned about it being too small and they assured me 2 3/4" was the number. They ran them on 900 HP Sprint car engines so I bought what they recommended. Just got them all back from Caps Coatings, NICE ! Called their tech and they gave me the rundown on breaking them in. They want extra fans on the headers when you fire them up. And told me if there is a fingerprint on them it will get baked in. Clean them with alcohol first. I am worried about installing them without scratching them all up. So they said to wrap them in blue painters tape first. Its going to be one big pain but should be worth it. |

After a long talk this morning I made my mind up that when we sell this property I’m punting this build & going another direction. |

Burns said 26” primary 8” of 2 1/8 to 9” 2 1/4 to 9” 2/38 use their collector (of course) with a megaphone. Bob Crawford built all our motors prior to us going full aluminum builds. He always said never go shorter than 28” on primaries or you’ll kill your torque. I talked to Frank @ AllPontiac yesterday & he said he uses 28” primary. My current headers are right @ 26”.
