JoeliusZ28's LT1 cam swap thread

[JoeliusZ28]

Yeah....11.5 is REALLY pushing it on pump gas even with FI and aluminum heads. You might find yourself battling inconsistant knock retard tank to tank depending on gas quality.

There are people that have ran over 12 on pump gas with these engine successfully. 11.5 is also the highest it could possibly be. its probably more like 11.3:1, i need to recalculate it sometime. And regarding the gas quality... I have run Sunoco 94 in the car whenever possible anyway.

The manufacturer of my cam recommended extra compression and said that as long as I knew how to tune well I could take 25 thousandths off of my heads to get me to 11.6:1. I took 20 off

The guy i talked to on LS1tech who is running nearly the same cam (his intake duration is 2 degrees bigger) and he has no issues with 11:5.1 compression on his own tune.

yea i saw his computer, it was kinda buried like everything else there! He had QUITE the machine shop in that garage. Ive never seen so many cranks and engine blocks in my life. My LT1 heads looked like a joke compared to all the BB stuff in there! Im very happy with the work he did for what i paid.

[Virtue]

yeah all those big block heads and race boat heads

the place is cluttered but he knows where everything is somehow lol

that's awesome, Joel! I love the garage PC -- that's a great idea. I'm constantly lugging my laptop out there.

OK, made some good progress tonight. Got the oil pan out finally, and the pump spring replaced. Unfortantely I broke the low-oil temp sensor in the process though.

I also got the cam changed out, so I am happy to say that I am officially in the reconstruction stage of things now. Gonna work my tail off on it this weekend, Id like it DONE in 2 weeks or so!

oh yea, updated pictures first thing in the morning.
