Thread: 305 in a bucket?

Tweet

Me and the kid went 305 sprint car racing this summer,he won the track championship. car with driver & ten gallons of alky weighed in at 1742. That motor would hike the front wheels on a good tacky track.
60 over 305 block,stock crank, 6.2 eagle rods, custom flat top ross pistons,total seal rings,550 lift schnieder flat tappet cam, block decked , stock 305 heads #602 ? no port or polish (rules) 184 intakes (unshrouds em) all light weight Fierra valves, Fierra light weight lifters, crane springs & roller rockers, heads milled,stock oil pump,cheap Ebay jap copy nascar style intake,750 holley homebuilt alky carb,vertex magneto. complete motor including machine work, minus fuel & ignition system cost me about $4.500 . I don't have any dyno numbers but I would almost bet ya that motor was class of the field ,a buddy had built a very similar motor with 30 over bore and 5.8 rods for his 305 sprinter he also did the 4 - 7 firing order swap, that one has dyno sheets @ 364 horses ( his word I haven't seen the sheets) but since done by a pro engine shop, cost a considerable amount more than mine. My kid can pull him on a straight away drag race ( I contribute it to the 6.2 rods ??)
We ran 27 shows this season,turned it 7200 rpm and I just finished getting it ready for winter storage, backed the rockers off and did a leak down wich showed perfect,pulled the pan and looked at a couple rod and main bearings and they looked very good although I will put new bearings in this spring. All in all I've been very impressed with these 305's..... Butttt still there ain't no subsitute for cubic inches...

Oh, come on Don---You know I'm a negative old poop!!!

i love the 305 in my 78 firebird. .060 over with headers, .cam = .454 - 290 dur. and otherwise stock right down to the 2bbl. Gets 18 MPG @ 80 MPH, and stomps the hell out of ricer burning punk kids. OH yah, I love shifting into first @ 50 MPH and grabbing a car length, thanks to my 2.41:1 rear end!

I think the Speed Pro pistons are much better.
I would like you to run one carb.
I think you would be much happier and have more drive time.

go with the Comp Cams Xtreme energy XE262H Its 218/224 dur at .050 and 462/469 lift and 110 lobe sep . I think this is also the cam the guy used in that you tube 305 . Do a little porting to your 305 heads . This is the biggest cam you should run in your 305 . It will give you max HP and not kill your torque . And you can go down to a 2800 stall and run a 355 gear . COOL

i like the cam choice,total performance told me not to run anything bigger than 287 gears because the car only ways 1600 lbs

sorry ,thats a 279 gear not a 287

As light as that rod is it still will run good with that XE262H CAM and your 279 gear . And I sill think the 2800 stall is better for your set up . 1600 lbs you are better off with a 305 . With a 350 that car would be like a street rail . With the 305 it will run 12s .

YEA, it only has a 10 gallon tank

I will take youre advise ,thanks
it will run 12s if im brave enough to stay in it
