Default TSP 402 with L92 heads and L76 intake!

I am planning a putting and a new engine in my car and wondering if there are any issues with stroker if I daily drive it. Oil consumption or durability?

No problems with mine. There were problems with the assembler at Scoggin-Dickey who did not put sealer on some head bolts that protruded into the intake ports. Oil was drawn into the intake chambers and puddled in the cylinders.

You might also want to examine the intake ports of the cylinder heads you get. Some porters open the chambers up so large that there are pin size holes that draw oil into the chambers.

Other than the first issue, my Scoggin-Dickey LS2-402 has not burned oil.
A good tuner is important.
The car gets good mileage.

Specs on the car are in my signature.

Yes, the large cam is very street-able. The tuner set it to idle at 1000 rpm, but I'm going to lower it to 900 rpm. I have HP Tuner software. I should mention that the larger camshaft and LSA is easier to drive than the 228/.585/112 cam I had in it. I've lost a little of the low RPM torque with the larger camshaft, but the car doesn't jerk as much when starting out. Gas mileage is still very good, actually better than with the smaller camshaft. Spending money on good heads is important and researching for a good camshaft is the heart of it all.

By your specs it would seem that you do not have L92 heads with an L76 intake on your car with those valve sizes and the cc's. Correct me if I am wrong.

505 at the wheels here, still have more mods to do to get the power up, and its on a decent size nitrous cam, and its fine driving every day, awesome getting up to speed on the freeway, lol, rings are gapped loose for the spray, and i dont burn any oil like i thought i would. i drive it to the track, go to the staging lanes, make my passes, and drive that bitch home, Dave Diluca at cdnperf.com built my shortblock, and he did a top notch job

My 402,l92 seem fine. I have a 248/256 112lob cam and it has no issues driving around town. It has a mess of low tq and fun to drive.
