Looking at the previous posts,some of you guys have some pretty extensive(&expensive)mods. What kind of HP #s are you making.
I'm 210, no major mods yet

A piece of advice for the 305... leave it in, put in thicker head gaskets, and then add a supercharger. Modify the supercharger (not too hard) to make 10-12 PSI and get bigger injectors and you will be killing cars left and right.

For the dollars involved (and the constant headaches) playing with the engine is too expensive... unless you have major dollars.

Just my $.02

I would probably get 50hp more if I added aluminum heads to my car (maybe 15ft lbs.)

A supercharger has crossed my mind, expenssive upgrade to handle all at once($5000.00). Ah maybe someday....

I'm not sure how much power my cars make.I'd guess low 400's for the Z28 and around 280-290 for the GTA.The Z28's engine is on stand right now.I just got the heads.As soon as its done I will be going to Zeke's or DynoPowerServices to run it on a chassis dyno.

Not sure what I have. My 350 is from the late 70's and it is supposed to be 180. I have added a mild cam, and all new internal parts plus the headman hedders. The machine shop guys thought it might be 300 hp. However I have never had it tested. It does go like stink but that is just me comparing a friends Z28 with a 305 AND NO MODS

 

Does anyone know were you can go see how much rear wheel HP your car puts out. And how much this costs?

1998 Yamaha WR400F
1988 Yamaha FZ750
1985 Yamaha RZ500
1999 Ski-doo MXZ600

 

Their are chassis dyno's in Scarborough (DynoPowerServices) and Montreal (Zeke's).Zeke's is SLP's Canadian outlet.

86 IROC-ZZ4... too much to list.

 

Since all Drive Clean equipped garages have chassis dyno's, I wonder if any of them would be interested in doing some after hours testing.....?!
