This is what I am going to do over the next 6 months to a year to my LO3 5.0 305 is it possible with a good tune to get in to the low 11s high 10s. I am committed to being a odd ball so I will stay with the 305 and not go with a 350 and stroke it. But let me know what all think and a supper charger or nitrous will be after this what do yall think will work better. I will do a DYI artical on the parts with pics as it all slowly comes in

thanks in advance yall

good luck

 

Not enough bang for the buck. Ultimately, it all come down to cubic inches.

 

I can appreciate U wanting to be different and not one of the sheep!!

If U are going to stay with a 305, it will take either some radical pistons heads cam combination and even with that U will be disappointed. I t will definately take a blower, turbo or nitrous or a combination of those to un the kind of time U want!

If I may make a suggestion, get ahold of Owen @ ARD, and set a time to go over there and run this by him and see what he has to say. DO NOT just try and call him and talk to him over the phone. U need to go over and sit down with him so he can show U some things!! Take my word for it!!!!!!!!!!

From I-10 and highway 6, go north past Keith Harrow till you reach Addicks Satsuma. Take a right turn and go about 100 yards down, and you will see the sign and it is located on the left in a business park.

 

thanks i hope for my can with nitrous and a root screw supper charger to be in the 9s so that is the over all goal i will call him on Monday and try to set some thing up with him on Tuesday my only day off this week

With the money you will put into your 305, I would ask Owen what other options he recommends. He is installing an Ls1 in my previously LO3 powered camaro which should get me in the 11s. But if you are set on keeping your 305 good luck.

 

that is my point, no mater what you do, you will have an impossible task to get that in the 9's, ive got my 408 ls1 with everything on it, and i just got a new cold fusion direct port for a 300 shot and i dont know if ill even get close to the 9's yet

 

nevermind, gonna say not worth it but you said you're an oddball so good luck.

 

i could always go with what my budy did and just take a 350ci block stroke it to a 383ci put a comp cam and lifters iron eagle platinum 215cc heads and the works be done with nitric for 5 to 6 k push 640 torque at 4500 rpm and push 600hp at 5500rpm and it would just about bolt right in to I will post all the bits to it but I really want that unique factor in my car but I may just have to sacrifice it for the power I want

 

U have slammed a couple of "niners"--does that count?
