212/218 low lift cam had great low end in my 5.3. Ran it for a bit with stock stall. I wouldn't go much over 220 duration cam choice with lsa of 112-114.
I appreciate the info guys.
So it would be a stretch to get 400hp out of a 5.3 with just a cam and bump CR? I thought you could get 100hp with just a cam swap?
I assume the stock injectors are 42lb?

Stock wouldn't be 42lbs...400hp at crank yes not that hard. 100 from a cam swap only would be a stretch. Haven't ever seen it happen. With more aggressive cam you could get more hp but would loose too much low end for your plan. Plus have to run a nice size stall to take advantage of the power band.
Gotcha, thanks!
So what about a TSP 220 .581 112lsa? Or could I go bigger? Id like to stay at or under a 2800 stall.
Would anyone how much I should take off the heads?
It needs to be kept in mind certain conditions. Are you talking about crank power goals or to the wheels? How tall are your tires and gears? If you are going 2800 stall then a 220/224 would be a good choice for something a tiny bit bigger. Anything larger than 224 is going to move the powerband up too high for your desires. Keep the LSA low around 112. A split duration cam will open up your power a bit wider so it comes in sooner and ends higher. I would take about .030 off the heads for a nice bump in power. 400 to the crank is possible. 350 to the wheels can be done.

A crawler is a very different animal as far as trying to figure power for. Honestly I don't have to have off idle power due to all the different ratios I can run. I can run dual t-cases with low gears in them, also run low axle gears and I run a TH350 trans, so I have three gears there. The lower ratios I have available, the more gearing options I have. So say my lowest ratio is 120:1 I can run an engine that makes its power at 3-4k RPM and be totally fine because at 3k RPM ill be moving 5mph.
I just want the most power I can have without running a really high stall.
Its got 42" tires, 4.10:1 axle gears, and will run a stock NP205. If I need more gearing, Ill add a doubler, ect. The thing is, with more power I don't need such low ratios, and can hit obstacles with momentum and wheel speed instead of crawling the best line. I'm more of a mat it and close your eyes kind of person, than a technical driver. I think its more fun my way. LOL
I am talking flywheel HP.
