ap72 clearance the rods, small base circle's are only good for lazy cams.

454C10 Plus you will need to use a small base circle cam or get your rod caps machined for cam clearance.

ap72 yes, but you'll need new pistons, a hone job, new flywheel, new balancer, and it all balanced... And of coure, rings, bearings, and gaskets.

Pontiac68bird If I get a 383 stroker crank. can I use my stock 5.7 rods that I have now?

ap72 I'm just an engineer, but I probably spend more of my money on cars than I should. And while it is not like going to walmart and picking up a box of shells a blower is a very cost concious approach for this guy. He has a solid short block and wants good street power. he could go out and buy new heads, rebuild the bottom end, get a enw valve train and end up with a 11:1 semi-race street engine, or for half the price he can make the same power only more reliabley and with more torque... A mini-blower is perfect for this situation.


As for the carb question- yes you can reuse your old carb but you will need to retune it, I recomend reading up on it, asking questions, and trying to do it yourself. It takes more time the first go around, but if you want to claim being a hotrodder I believe you should have dirt under your finger nails.

TroyBoy What kind of jobs you guys got? You throw around buying blowers and buying new heads,intakes,etc.like running down to Wal-Mart and picking up a new fishing lure.You guys must eat TV dinners and ride bicycles to work
10-09-2008 08:01 PM
Pontiac68bird true. Well i need to look into these blowers a little more. I do like the idea of popping the hood and have it sitting there.When you buy the kit is there anything else needed? Can I use my carb ?
thanks you guys have been a great help

ap72 you can have a good "rump" if you want it, but that rump is just wasted power and fuel. Some of the bet street machines have a near stock idle quality. To get that rumble with a blower you can simpley narrow your LSA to 106 on a cam and run about 10 degrees more exhaust duration than intake. something with about 218/228 @.050" with a 106 LSA and a blower would give you a nasty sounding idle and an indescribable amount of mid-range torque.

Be warned though, you will loose about 25% of your precious MPG's. And yes, I overlooked your edel heads- sorry about that.

a lot of people pick a cam for sound, and there's nothing wrong with that, however the best sounding and the best performing cam are two different things.
10-09-2008 07:22 PM
Pontiac68bird i really would like to do a big cam just because of the sound. I Know a blower would be better for driving but if I was going to do something for drivability I think I would just go with a ls1, 4l 80e and then I would have fuel injection and over drive. I want something that has a lot of rump. I want people to know its coming
10-09-2008 07:16 PM
454C10 you can run 11:1 cr with pump gas if the cam is big enough and has enough stall and gear.


The difference with a blower is the engine would make the same power but with a much smaller cam. And a mild cam will have a smooth idle and you can run a stock stall and gear. Plus the low speed toque would be twice as much. So you save some cash on gears and stall and it makes a much nicer street car. Plus you could use the engine you have since it is new and has 8.5:1 cr.

Performer heads are better than vortecs. I'm sure ap72 missed that in your setup.
10-09-2008 04:11 PM
Pontiac68bird vortec heads would flow better then my edelbrock?
10-09-2008 04:02 PM
ap72 I would go with a supercharger kit, and maybe a cam depending on what you're currently running- it may not be that bad to use the one you have now though. And a supercharger with a healthy cam will put you at 400HP without even trying- I would look into maybe going with a Vortec head setup before you buy the supercharger though, as you can keep from buying two intakes. The Vortecs will really help your engine flow and 500HP wouldn't be hard.
10-09-2008 03:37 PM
Pontiac68bird this is a street car but it does not come out often. With 11 to 1 would that require some sort of race gas. Or at least a mix of 91 and 110? I like the idea of the blower and it sounds like that can get me just as much power and doing the stroker. i would like to be somewhere in the mid 400's on horsepower. The motor now doesnt even have 2000 miles on it. It runs great just want more power.
thanks guys

ap72 I misquoted the cost of a new kit- its a little over 2 G's

http://store.summitracing.com/partde...5&autoview=sku

As stated though you can find a used kit for less than a grand- or nitrous which is $500 or so for a 150 shot on a carb.

Or the self fabbed turbo setup- which most people can do with some back yard ingenuity and about $1000.

All of these are cost effective and will supply more power than your drivetrain should recieve... So look into buyig a built tranny next and a 12 bolt.
