Is that piston p/n supposed to be L2252AF30?

F-BIRD'88

I'd finish it off with Summit 200cc S&S aluminum heads # SUM-162111
Edelbrock Victor JR intake hand port matched to the heads.
Holley #4779 750cfm DP carb. (add rear jet extensions)
110GPH minimum fuel system 1/2" fuel lines
Isky 292H Mega Cam Isky #201292
Summit #G6905 aluminum roller rockers.
ATI 10" Treemaster custom 4000 stall TH350/400 torque converter
1-5/8" long tube headers, 2.5" Y'd into a 3.5" or 4" "Big Mouth" exhaust.
Summit # SUM-850055 distributor Summit # SUM-850600 CD ignition
w/ Summit # SUM-850500 E Coil
"lockout" the mechanical advance curve (34deg timing BTDC,full time)
Limit vacuum advance to around 12-15deg at high cruise.

your Th-350 and 4.10's are fine.. get some sticky tires.

^^ not a bad build at all. just maybe go 1 3/4 longtubes but 1 5/8 will work well.

stock crank and rods i'd keep rpms down below 6500 or so if limited use. they wont like to rev high but a cam like 280-290 duration advertised will peak by then anyway on most builds

Whats your budget for this build? Any ideas of what power you want?

Low to med budget have a set of 76 cc heads #464624 which would give me 10.20 compression 172 cc intake runner 2.02/1.6 stainless valves screw in studs and plates springs to 565 lift. need a intake to fit under stock hood and a 750dp and cam, power enough to run 7.9 in eight this is a new build for a 1985 LITTLE OLD LADY CAMARO ONLY DRIVEN ON SUNDAY TO CHURCH CAR which has a 700r4 now and will receive a auburn posi rear end moser axles and eitheer 373 or 410 gears street drag radials also a 3200 stall converter thanks

A 750cfm DP for a mostly street driven 355 under 6500 rpm is way overkill. I'd go 650 DP. And same for a Vic Jr intake is also not necessary...Performer RPM intake is a perfect street intake.

And whoever suggested the 1/2" fuel lines, you do know that it's only 3/8" going in the fuel tank right? Unless of course you plan on redoing the sending unit lines also.

Is 172cc intake runners gonna choke this motor?

xyzman

Don't know just asking for feedback, heads are not purchased yet what would you suggest

I'm still waiting to hear if that was the correct piston p/n you posted. I couldn't find anything with that number, but the p/n I posted is domed pistons. Is that what you're using?

172cc isn't going to "choke" the engine, but later design heads would make it run better.
