I have had plenty of engines over the years and those are the two most important questions you must answer before you start.

Any of these could be considered drag racing engines, but are drastically different. Goals and budget... 8's, 9's, 10's? -Dustin 67 Dart, 9 second, 392" G3 Hemi 68 Barracuda 340 F/SA

Mopar based motor with one carb. on race gas Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

I have had plenty of engines over the years and those are the two most important questions you must answer before you start. Well my engine in my car was not what it was supposed to be. I pretty much have to start over. I've sold the motor already. I'm in pretty deep and cant back out now. I'd love like hell to be 8.0's. But like I've said before, I don't want to be inside this thing all the time. I know it can be done. I wanted to mainly hear what you and the other Mopar guru's would build and how and what you'd use etc....

B G Racing master Joined: Mar 2006 Posts: 9,910 Eighty Four, PA	That's a loaded question We see many racers that build beyond their budget and abilities because they are never satisfied once they attain a certain level of performance.They never consider the cost of maintaince and repair at higher performance levels nor do they consider all the other related cost associated with the faster classes.The cost of maintaining and operating a 10 second car and a 8 second car are miles apart.As mentioned earlier get a solid plan of what you want to accomplish,plot the venture step by step as far as cost verses your budget.Remember to include any and all other factors besides the engine.Usually engine upgrade means chassis and driveline upgrades.The cost can sprial out of control. Most importantly know your skill and ability to be able to handle a faster car.Many get in over their heads find that they get a lesson they didn't intend on learning. What ever you do think it through before starting the project and good luck. [IMG]http://i430.photobucket.com/albums/qq21/ajcasini/max_zpsdppwd9km.jpg[/IMG]

Track only, then what class, index are you gonna run or is it a bracket race or just a TnT toy? If you also want to drive on the street then things like cooling, fuel type and capacity matter. What gas are you planning to run? Big difference cost wise between 93 pump swill and C-16. I would suggest building for the cheapest fuel that will accomplish your goals. C-16 in a street driven car isn't very practical, especially if the tank is small like a race car. So with a goal in mind, with the weight and build os the car/chassis you can estimate how much and what kind of power you will need. Figure those things out then you can ask what you should build, IMO. Edit: I typed that in before I read the above few posts which said basically the same thing. If your heads do flow 420 then they should support plenty of 572" power. My guess is 900+, or somewhere around that. The maintenance thing is huge. You wanna be thrashing on the motor between runs or relaxing and enjoying the race?

Al_Alguire I Live Here Joined: Jan 2003 Posts: 19,378 Las Vegas	Well still kinda open ended. I went 9.04 at 150 in a 3470lb 67 Valiant with a set of originals that flowed 415-420cfm with a stock block, Ohio crank, GRP rods, Indy oil pump and Bullet roller with 286/290 on a 113lsa with life at @800", unported single 4 intake and a out of the box Holley Dominator. Was a fairly budget minded build and in a 2800lb ish car would certainly run 8's with no issues. It was a father son project when my kid was still playing HS baseball so racing time was limited. We built the engine to get an idea on what would work well with plans to upgrade some components later to better pieces and more power. Made some cam and carb changes along the way and had a good handle on where to go with it. Ended up deciding to go super class racing instead after baseball and eventually sold the car. BTW if anyone in the Lincoln, NE area knows the car I would like try and get it back. My point being some sort of budget it required to make some decisions on what direction lead. My advice is buy the best components you can afford. Running 8's at 2800lbbs is not rocket science. 900 hp will get you in the 8's easily. Your heads can support 950 relatively easy but if you want more you will either need to spin it harder or look for better heads. 950 in a great working car at sea level will net you sub 8.50 times. In Boise maybe 8.60's. FWIW my Barracuda at 2975 went 155 in Boise at the S/ST index of 11.15 "I am not ashamed to confess I am ignorant of what I do not know." "It's never wrong to do the right thing"

Meanwhile the engine in the Barracuda was closer to $35K. There was maybe 125-150hp difference in them. But those HP come at a price for sure. I am currently working on a new bullet that will be 150ish HP better than the last one and it will eclipse $40K. If I had a brain I would have bought a used 5.0 bore space deal and freshened it up. I would be dollars ahead and have more power than this Mopar will make. Call me stupid for keeping it all Mopar..Just saying it can get expensive very quickly.

What is the chassis best 60ft and ET/mph? An Enderle alcohol injection would be nice, I like my Ron's Flying Toilet injection too, but an alcohol carb will get the job done.
