Re: NEW 406 hates my back tires
Yep that should do the trick.
I built a 385" and 11.9 compression with 175cc heads and the comp 280H magnum cam.
Big mistake.
[email protected] .050 on a 110 LSA installed 106 intake centerline.
That thing was brutal on tires.
my little 350" before that would hook up very well and this thing was Impossible to hook to the pavement.
Rolling at 50 I could roast them.
I could not imagine how well yours is doing.
I bet it is fun

Re: NEW 406 hates my back tires
Like I mention before. 406 is an animal, total beast. My tunnel ram 406 with 280 comp cam and AFR227 with 11:1 forge slugs, with two 390 CFM holleys ( instead of one 780 CFM) and a TH350, 3500 stall converter and 410 gears. It also hates my rear tires. They are begging for mearcy.

I also have the "small" 195 comps on my 91 octane 406 but with a modestly sized SR.
Freight train is what comes to mind.
I am in the process to start to have another engine built for boost this time.
Going to be 400ci or larger aftermaket block this time.
Little M probably.
No way was I going smaller.
Not coming from the monster I had.
I could dispute the whole bigger thing with MY personal experience but it's not worth it
Enjoy your "small block"
