Mid 13's?

Just a curious question, my freind took his B18 civic to the track and ran 14 seconds. Im wondering what it would take to move a Long Box 2wd into the mid 13's. If you guys have combos that do that, please let me know what you did.

Re: Mid 13's?

Small block or big block can both get you where you want to go. But it depends on what drivability your looking for..and how much you want to spend. Either way..won't be cheap

you could do it with a set of AFR or Profiler 195 cc Heads
Comp XE274 or XE 284 or a similar Lunati Voodoo Cam or Roller Cam

Flat top pistons, Air gap or Vic Jr intake , 750 CFM Carb...
you'll need a 2500 -3000 RPM Converter 3.73 or higher gears
Good ignition system

Don't Scrimp on heads... Most of your horsepower comes from the heads.

Why not a 383 ??? it is just as cheap to do a 383 as a 350

Re: Mid 13's?

Thanks Jr! What about a 400 block instead of a 383? 400 with vortecs, ported and polished, planed. RPM air gap, and a 750 carb?

Yep, I have a 400 in mine now.... you'll spend a lot of $$$ getting those Vortecs up to snuff, and you still would not have the performance of a Profiler or AFR .. you'd be better off to start with Profiler 195cc Check out this link
I bought a set of the 210 cc for 1300.00

Re: Mid 13's?

just go with the newer technology small block...and LSx. A 6.0 with a few bolt ons would get you there. You don't have to go EFI either....

Re: Mid 13's?

they look like a real nice head, and probabley bang for the buck. But what kind of porting can be done to vortecs? because i have a set now sitting on a 96 vortec 350 that i may considering redoing.

Bore it .060 over
flat top pistons
headers
RPM air gap intake
Edelbrock 750
Carb spacer
Lunati Cam (not sure yet) still want to daily drive it
B&M shift kit Th350 or Th400?

Re: Mid 13's?

Porting is not cheap! here are some prices for just porting, and that is not including Hardware... Rocker studs, Valves, retainers, locks, seals, etc...
it makes the 1300.00 look pretty good
Cylinder Head Porting from Dr j's and speiers racing heads

Includes the following

Fully radius short turns on the intake and exhaust
streamlined guide bosses on intake and exhaust
maximized push rod pinch opening
bowls blended to
gasket matched
Before and After flow testing

At Dr J's Performance we do not believe on individual stages of porting, because it does not benefit the costumer. Our goal is to provide the customer with most amount of performance per dollar spent. Every head that leaves Dr J's performance is ported to its maximum potential.

Aluminim Heads starting at $ 700.00
Cast Iron Heads Staring at $ 825.00

STANDARD PORTING* This includes valve job and all the critical areas sized to your
combo, throat, bowl porting, and chamber finished. Exhaust port cleaned up. The areas
worked are then blended. This is NOT a full hard rolled port. I'll give you the flow sheet
for future cam choices and combos. 18-20 hours of grinding and flow bench work. Prices
start at $1000 for SBC
FULL PORTING* All out porting and velocity profiles. This includes multi angle
valve job, hand blended. All of the above with a fully hard rolled intake and exhaust
port and chamber. Exhaust port exit is sized. Exhaust port is FULLY polished.
Contouring the guides. Port mapping to achieve proper velocity. Chamber is sized to
bore. Attention to detail is above and beyond!! Prices start at $1350 for SBC.
*The valve seat area is the most critical part of the flow path in a competition cylinder

Re: Mid 13's?

Re: Mid 13's?

Didnt think that much was involved, how much power are vortecs able to make? and what size of a cam can they handle?
