Ok so my younger brother wants to race and i wanted to see if anyone had predictions or advice. My car is a 91 Camaro z28 with a 350 TPI, its an automatic. My brothers car is a 91 Firebird with a 305 TBI, its also automatic. We are going to race in drive first then we are both going to manually shift. Please give predictions/advice for both races.

 

The Z28 will always win. 245hp in the 350 TPI as opposed to the 170hp of the 305 TBI - no need to even prove/disprove - just an excuse to get a ticket.

 

Yeah ive been telling him the z28 has a bigger engine and more hp but hes that his cars design is more airodynamic and meant for speed.

 

The Camaro should be a high 14sec car. I know for a fact a stock 305tbi auto will run someware in the low 16sec range.

 

ok thanks for the info. would it make a difference if he manually shifted and i just stayed in drive or would it be the same outcome? if i get enough info to prove him wrong i wont have to risk messing up my car to race him or maybe he will still want to race, either way. thanks

 

The 305tbi has a "peanut" cam. That same cam is in my car. It makes peak horsepower at 4000rpm. Manually shifting a 700r4 will only have an effect if you're trying to DELAY the shifts otherwise it'll shift around 5000rpm so it will either not make a difference or make him slower if he shifted. Also, in case he wants to take it to the highway hoping his better aero will get you his car has a speed limiter, yours dosn't.

 

ROFL!! You'll beat him.

 

Agreed 100% with rest of above posts ^^

350>305 stock for stock anyday.

Any of you two have anything done to the cars?

 

If his car had a t5 tranny and 3:73 gears and had perfect firm shifts he would hang with you all day long.

 

both cars are completely stock Samurai. thanks for the input guys

 

Save your gas and don't even bother. If his car was a 305 TPI 5 speed it would be a different story and a good race. The 305 TBI in stock form doesn't have a chance. You should give him a head start if you end up racing him. It's the only way it would be fair.
