i have a question, i am building a 383 stroker for my 89 camaro, it had a 350 TPI just wanted more power and torque, but now since the engine is almost done i am wanting to go old school with carb, i got a HSR but never use one, and i know about carbs and it would be easier, so what are the pro and cons of running the carb over the HSR and which is best for a 450hp stroker. Come on now not all at once. Decision Decision

Carb is cheaper. Less required to tune. Did I mention cheaper??

However.... If this is a daily driver, the HSR will give better drivability, better economy, (if this is even a concern....) and is more forgiving of ambient conditions. You already have one, so that cost is covered. You would probably want to pick up the stuff required to do your own prom tuning (see the DIY prom board, on this site, LOTS of useful information there, and VERY helpful people.)

Which would make more power? I don't know. Either option can be dialed in for some serious horsepower, depending on your combo. In the end, it is up to you. Me, personally, I would do the HSR.

By the time you buy a carb ($300-400), intake ($125-200), distributor ($125-250), fuel pressure regulator, plumbing, TCC lockup kit, and do all that work, I don't see where it's any cheeper than the HSR.

The HSR will make more power than some carb setups and less than others; say, more than a Performer intake and a Holley 1850, but less than a Brodix HV1000 and a Holley HP950. It's meaningless to claim that the HSR or a carb will make "more" power, without qualifying what carb setup you're running.

Plus of course, carbs are more forgiving of the types of modifications done elsewhere in the engine to increase power, specifically THE CAM. Meaning, ULTIMATELY, the HSR reaches a limit, but carb setups in general can get past that.

I believe if I already had a TPI car, with all of its FI facilities installed and operating, the HSR would be near the top of the list of choices.

I would use a MiniRam, however, for MAX POSSIBLE power out of a side-draft TB type of arrangement.

If I were in your shoes, with a HSR sitting on the shelf, I wouldn't be sitting at the computer typing on the Internet. I'd be out in the garage turning intake bolts. ANYTHING to get that LTR crap off of my motor.

thanks guys, i knew i could find some good feed back, I think i'll keep the HSR like you said i still have all the Fi set up and wiring, i just need to get the best tune possible, i think the best way is dyno tunning, i know a good place in louisiana, since i dont know much about houston

who dyno tunes our cars in louisiana.. im located in new orleans and i need a tune.. thanks..

you might want to try allen futrell in Baton Rouge or Thunder Racing in BR also

neither one does it. they say its too much work.. go figure..lol
