I am going back and forth on whether or not I want to keep the stock 302 or swap it out for a 351w. If I keep the 302 I am going to bore it and stroke it. How much horse power can you get out of a 302 bored 0.030 over with good cam, intake, and everything else. Looking at getting around the 400 mark at the rear wheels. Does anyone now if this is possible?

Getting 400 h.p. out of a 302 is achievable. If you bore it over .030 and run a moderate cam, you'll get about 350 h.p. Figure you port the heads a bit, and and mount a decent four-barrel on it, then you've hit around 400. Lets not forget that you can buy a 347 stroker kit for it. Then you'd be past 400 by a bit. 351W's can build 400 easy too. It's just a matter of what you like better, 302 or 351.

400 hp at the rear wheels means 420 to 430 at the crank. You will need good after market heads, a good cam, dual plane intake, 650 cfm carb, headers and good ignition to make that kind of power from a 302.

Check online under Crate engines. Most builders will list components used to make a variety of horse power from small block fords. This will give you a good idea of the components needed to make the power you want.

What do you consider a moderate cam? also what are the RISK you take by redoing the heads on a 114k engine and putting back together for a while, not quite ready to do a complete rebuild. I posted this before but got no reply. so I'm hitching a ride on this fellas thread.

I am looking at boring it .030 over and stroking it to 347. Also looking at Victor Jr. Heads. Looking at a 4 barrel 850 cfm carb. Not sure what type of cam would be best or what flex plate would be best? Will the stock trans be up for this power or should i look at a race ready on? Should i use a dual plane intake or single. Looking at Edelbrock intake. What type of distributor would be the best fit for the 302?

my 302 in 66, gt 40 heads, dual plane performer, 0.30 over, mild cam, roller rockers, holley 600, msd hei ignition, hooker headers, c-4 with shift kit and 9 in rear end everything port and polished,balanced,and blueprinted 2500.00 and you get 390 at the crank and around 360 370 at the rear wheels on the dyno.

66 ....... thats not bad ............ I just may use the same formula with my 68

850 is to much carb for a smallblock you'll spend a lot of time adjusting and adjusting (air, fuel, timing, vaccuum) ive got a 69 camaro with a 454 and went with a 850 on it ran like **** adjusted constantly finally went down to a 650 and a little timing adjustment and she ran smooth as silk, 600-650 is plenty for a 302. thats just my expereince and opinion.
