If i put in a 383 stroker with .030 over pistions rather than stock what would that make my cid? ( the 383 cid is advertised that it will make 383 cid with stock size pistons)

 

???? a 383 is usally with a .030 overboar, but i guess it would be around a 388

 

No, a 383 is a 4.030 x 3.75 motor, I'm going 4.020 x 3.75 which is a 381... a 388 is a 4.060 bore, then your pushing it, walls are gonna get thing and you'll pay for it in the end.

4.000 x 3.75 = 377

 

ok im lookin to put a 383 stroker in and then do a .030 overbore then i will be putting in a hotcam kit with LT headers and a catback flowmaster american thunder exhaust. I will have my ecm programmed for the setup. How much power/ torque can i look forward to? ( i already have a k&n aircharger, the heads exhaust ports were smoothed and the head was plained .008)
Thanks for all the help.

 

thats almost exactly what I have in right now. It has 800 miles on it and I'm gonna throw on my cutout and LCA's this week. I plan on taking it to a Dyno in about a month. I'll let you know.

 

Oh ****, well your already .030 over right?

 

what exactly are you running? How much more umph does your motor have since the 383 is in place now?? See my plan was to buy a 383 stroker kit that used a std size piston but instead im opting for a .030 over piston to try to give me a few more cubes? any close estimate of the cid in the end?

 

Dude I spelt it all out for you in my first post.

4.000 = 377ci
4.010 = 379ci
4.020 = 381ci
4.030 = 383ci
4.040 = 384ci
4.050 = 386ci
4.060 = 388ci

 

are you talking about the stroke or the bore?

 

Asumming you have a crank whose stroke is 3.81" and a bore of 4.00 to get 383ci. A 4.030" bore with the same crank (at 3.81") you would be 388.79 ci.

 

thanks for virtually slapping me in the face and waking me up....sorry its late ...... thanks.

 

Were you talking to Larnach or me???

If it was me I got Eagle 4340 crank and H-beam rods with SRP pistons. My motor has a crap load more UMPH. My son was in it the other day and I nailed it. He tells me "Dad...why does my head hit the seat so hard now?" I asked him if it feels like its faster and he said "oh way faster".

You'll have a 383.

 

nice.....seems like people think the HOTCAM is a great compliment as well as the cc305 to a 383.??

 

Yeah, I saw a hotcam guy with a 383 put over 410rwhp down.

Not bad at all.

 

I love it. I'm glad I didn't go bigger cause this is my everyotherday car and I didn't want it too raunchy. I can't wait to get her to the track in the next couple weeks.
