thanks man

i need to get some slicks i think lower my 60' time to below 1.9 and hopefully get into the high 12's (key word hopefully) but i still have alot of tunning to do yet on the car i just got the carb set and now im working on timming and the timming curve then i will have to go back to the carb since it will be different cuze of the timming maybe if i get it all set i will see some 12's but i still need to do something with my 60' foot i dont think its that bad but there is room for inprovment in there i think

Two words, torque converter . You need one if all you are running is a stock type converter. Also, kind of a smallish cam for a 377ci small block. Those are the only two observations I made right off the bat. All else looks to be right on track.

umm 377ci? its all standard its a 350ci motor im just wondering where you got the 377 from and its quite a medium sized cam for a 350 you have to remeber its a rollor cam

yeah i think that will be my next purchase is a tourqe converter just a small one like 1500 stall liek you said before i dont have that much of a cam so having a huge stall would be a wast of power im thinking in the 1500 to 2000 range should be about what i need since the start of my power is at about 2500

If your cam is rated 2500-6500 your probably gonna want like a 3500 stall....yes you read that right. smae parameters as my old cam and got down into 1.72 range 60'. It sounds like alot, but if you stick with a 10" convertor it's still going to be plenty tight to drive around on the street with little to no noticable difference over what you have now. Just menas when you mash it and flash the convertor it's going to be closer to your peak torque and get you going that much faster.

better do alot of tweaking In about 2 weks the new 388 is getting dropping into place. Paperwork says high 10's but I'm hopeing for mid to low 11's to be conservative.

Steel Crank Stroke 3.75
I pulled it right from your supplied specs above. A 4" bore motor w/ a 3.75" stroke would be 377. If it's just a 350, then it will be a 3.48 stroke crank.

Thank you! :hail: Someone who knows what they are talking about. I ran a 3200-3400 stall w/ the same sized cam and it delivered low 1.7 60's on BFG drags. My old cam spec'd @ 270/276 adv., 218/224 @ .050", and .495"/.502." lift on a 112 LSA. It was in a 350 TPI motor. It drove with great street manners, and still delivered mid 20's MPG on the freeway.

NP, wasn't a dig against you - I just naturally figured that was the ci of the motor seeing a 3.75" stroke crank listed.

Maverick, couldn't that motor use a bigger carb for more power, like a 750?

possably but acording to barry grants websight its the recogmended carb for the aplication ive thought on it and im still running stock jets in the carb so i will play with that sometime this year allso i see alot of people over carb there motor but thats not a concern here just someting i allways keep in mind sometimes more isnt allways better but im sure i could use the air flow of a 700 or better carb with the 2.02 valves and so forth so it allso might be somthing i will experament with the summer

Just dont tell that to my old 355 that picked .4 up once I took off the 750 and stuck the 830DP on. And then picked up a wee bit more when the 950HP replaced that Dont know how many guys argued with me saying the 830 was too big, and now the 950 which actually only flows 830 wet cfm. Everybody can keep they're math equations, I stick to the black and white at the ticket booth. Givr'er more fuel I say, if your gonna buy a carb forget the 700DP-no hop up parts for it, at least invest in a 750DP, and if you can swing it at least a 750HP, but if you want a good all around carb you can grow into, 950HP hands down.

2.02 valves dont have squat to do with carb sizing. It's how well all your componenets work together. I've been here and done this starting with a 600 VS, 700DP, 750VS, 830DP, and now 950HP. Just like evolution the times got better not worse. Worse thing to happen, you load up the plugs street driving. Anybody that tunes for peak track performance with a holley knows there is no middle ground for street/strip. Your either going to run right on on the street and lean at the track, or just right at the track and fat in town.

With the right combination you should/a been smokin me but I run a carb that's too big so what do I know, lol!!
