What pump would you recommend? I have a new tank, 1/2" pickup, 1/2 line and want to do it old school with a mechanical pump. I have a Clay Smith pump, but it requires too much block grinding to make it fit. Any recommendations on a fuel pump that will feed 600+ horses and will bolt up without any grinding? Thanks

Well race pumps makes a neat unit. Suppose to feed everything from a lawnmower to a pro stock, but it's pricey and needs a regulator.
Edelbrock pumps claim to support 600HP (110 GPH). I put one on the Hemi. It fit with no grinding.

I used the Carter 120 gph pump with 3/8" line..not sure how well it would work with the 1/2" line. Too bad you could'nt have used the CS pump...others have used them and said they ground a notch in the block to make them fit.
Yeah Dave. The Clay Smith pump is a nice piece, but I would have to grind almost 3/8 of an inch into the block for it to fit. Thats a little much for my liking.
I did'nt know that when i bought it. Ya, I dont blame you, thats a pretty big chunk. I have heard the Edlebrock pump is almost as good as the CS and it sounds like it fits better.

I've been using the Carter mechanical race pump with the factory 5/16 fuel line. On 91 octane and a 100 shot of NOS teed out of after the pump I have run 11.20s puffing black smoke at the finish line. I couldn't get my mechanical fuel pump to pull through a 1/2 line on my cuda years ago.
I stepped up to a 3/8 line just today actually...for the new E85 motor. The 5/16 line held up for 12.0s on the E85, but the new motor went 578 horsepower, which is about 60 more than before...should run 11.50s this season.
Keep in mind that the observed horsepower was only 420, which will be about 440 at the track.

I have a clay smith pump on my car and i called and talked to the tech there and he said just to hack away at the pump (which i did) you really don't have to take that much off once you really get it on there and see what needs to be taken off. my car goes 10.40's and thats the best pump i have found so far (read constant 6.5 psi through the stripe) i had a carter street/strip pump on before with stock 5/16 line and pickup to start (car went 10.90's with that didn't have a fuel pressure gauge to tell if it was running outta fuel) upgraded to 3/8 line and pickup (car went 10.60's with that and had about 2psi going through the traps) upgraded to 1/2 line and pickup and the clay smiths pump (car currently has gone a best of 10.42@129 with constant 6.5 psi throughout)
I can get you pics if you would like

Just waiting to run the 605" down the 1/4 (4100lb 68 charger  ) , using a Carter mechanical 120 gph feeding a 1050 dommie with 3/8 fuel line for the street , got another 1/2" line also feeding the carb from the cell (leccy pump) , will run it down the 1/4 using the Carter just to see the results , have some valves on the fuel lines so i can switch from stock tank to cell. Just be interesting to see the results , even though i know the Carter ain't gonna cut it , although have'nt seen a problen on the street yet (fuel pressure dropping off) , driven it pretty hard too.
