anyone trap 110mph on stock heads N/A?

was just wondering if anyone is running that fast on stock heads N/A. was researching some different cams and it seemed like most would be around 105-108mph on stock heads. if you've reached this mark, how are you doing it?

I am trapping 104 with stock heads and cam. I have a friend with cc306 cam, heads havent been polished or ported, but has bigger valves installed and he is trapping around 113 mph i beleive.

I trapped 110.51 with stock motor, bolt-ons only. Car weighed 3715lbs, and its a 6spd. I had the usual bolt-ons. Headers, cat-back, K&N FIPK, MAF ends,52mmTB, msd6al, skinnies, ET streets, LT1 edit..etc

reason i ask is i'm looking into getting the 218/224 comp cam and longtubes and a tune. will do gears at some point when summer rolls around too but i was just wondering if 110 without headwork was possible.

I don't remember what it weighed that day, but I did have slicks and skinneys on. I would guess around 3600 w/o me (200+)

I also had a custom X-pipe exhuast that took me from 12.60's at 106 to 12.20's at 110 that day.

Also had a 52 mm TB and en Ed wright tune.

I have trapped a little over 110.15 so far with stock heads and cam. Next I plan on adding 1.7 roller rockers to give me an added 1-2 mph along with some more tuning. I am expecting to run mid to high 112 trap speeds B4 I go into the motor and add a cam. I also have a goal to break into the 11's with no cam too but will need much more suspension work.

L8TR,
