Im probably gonna try it on 87 octane as 9.3-9.5:1 isnt super high, might take a little timing out of it. 3-5 degrees is all, (ran 38 total on old setup at 8.6:1
Sorry, I'm not fully up to speed yet but learning. 3-5 degrees out of the distributor timing or the cam? 38?
Speaking of which, is there a consensus on a best cam for Tim's pistons? I imagine with the higher compression lobe seperation is pretty important to get right.
Sorry about that, i meant 3-5 degrees from total ignition timing, and 38 is just where i was running mine at. I would start pretty conservative on ignition timing and add as necessary.
As for cams? It all depends on your usage and where you want your power band.
I'll figure out what I want and go from there. I'm just looking to run a mild tune more focused on low-mid torque and economy. I figure 600-650 cfm carb, intake (have 2171), cam and pistons. Sticking with stock exhaust manifold and pipes for now.
I want a motor with more pep than stock but without risk of throwing rods or crushing springs.
Just about any cam over maybe .450 lift i would recommend springs as the stock ones arent that great to begin with lol. Rods probably wont be hurt up to 6000 the bolts are the true weak point in them as they have to stop that big ol piston and rod assembly thousands of times per minuite. I went to some ARPs and had big ends resized for about $240 but stockers should be ok on a mild setup. What cams are you leaning towards if i may ask?
I really have no idea. I still need to research the best now that I'm leaning towards the higher compression, before it was the Summit K5200. It seems like a decent mild cam with good reviews. 282/292 0.486/0.512. not sure how it will respond to the pistons. The lunati street master was my other pick but they only recommend it up to 9.0:1 compression.
